Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see?

How many vehicles did Tommy see? ** He saw 25 total vehicles because 12 plus 13 equals

<<12+13=25>>25. How many wheels did Tommy see? ** He saw 100 wheels because 25 times 4 equals <<25*4=100>>100. #### 100 Stephen has 110 ants in his ant farm. Half of the ants are worker ants, 20 percent of the worker ants are male. How many female worker ants are there? How many worker ants are in Stephen's farm? ** Worker ants:110/2=<<110/2=55>>55 ants How many male worker ants are in Stephen's farm? ** Male worker ants:55(.20)=11 How many female worker ants are in Stephen's farm? ** Female worker ants:55-11=<<55-11=44>>44 ants #### 44 At football tryouts, the coach wanted to see who could throw the ball the farthest. Parker threw the ball 16 yards. Grant threw the ball 25 percent farther than Parker and Kyle threw the ball 2 times farther than Grant. Compared to Parker, how much farther did Kyle throw the ball? How far did Grant throw the ball? ** Grant threw the ball 25% farther than Parker. If Parker threw the ball 16 yards, then Grant threw it 16*.25 = <<16*.25=4>>4 farther How far did Grant throw the ball? ** In total, Grant threw the ball 16+4 = <<16+4=20>>20 yards How far did Kyle throw the ball? ** Kyle threw 2 times farther than Grant so Kyle threw the ball 2*20 = <<2*20=40>>40 yards How far did Kyle throw the ball? ** If Kyle threw the ball for 40 yards and Parker threw for 16 then Kyle threw the ball 40-16 = <<24=24>>24 yards farther #### 24 A farm is growing corn in 2 fields. One of the fields has 13 full rows of corn cobs, and the other field has 16 full rows of corn cobs. If each row contains 4 corn cobs, how many corn cobs has the farm grown? How many corn cobs are in the first field? ** In the first field, there are 13 rows * 4 corn cobs/row = <<13*4=52>>52 corn cobs. How many corn cobs are in the second field? ** In the second field, there are 16 rows * 4 corn cobs/row = <<16*4=64>>64 corn cobs. How many corn cobs has the farm grown? ** So the farm has grown a total of 52 corn cobs + 64 corn cobs = <<52+64=116>>116 corn cobs. #### 116 Olga has three stripes on the side of each of her tennis shoes. Rick has one less stripe per shoe than does Olga. But Hortense has double the number of stripes on her tennis shoes as does Olga. In total, what is the combined number of stripes on all of their pairs of tennis shoes? How many stripes does Rick have? ** Rick has one less than three stripes, or 3-1=2 stripes on each tennis shoe. How many stripes does Hortense have? ** Hortense has double the 3 stripes that Olga has, or a total of 3*2=<<3*2=6>>6 stripes per shoe. How many stripes are on all of their shoes? ** Since each of them has two tennis shoes per pair, then the total number of stripes on all of their shoes is 2*(3+2+6)=<<2*(3+2+6)=22>>22 stripes #### 22 Frank bakes two trays of cookies per day, for 6 days. Frank eats one cookie each day to make sure they taste good. Ted comes over on the sixth day and eats 4 cookies. If each tray makes 12 cookies, how many cookies are left when Ted leaves? How many cookies does Frank bake each day? ** Frank bakes 2 * 12 = <<2*12=24>>24 cookies per day. How many cookies does Frank bake in total? ** Frank bakes a total of 24 * 6 = <<24*6=144>>144 cookies. How many cookies does Frank eat? ** Frank eats 1 * 6 = <<1*6=6>>6 cookies. How many cookies are left after Ted leaves? ** After Ted leaves, there are 144 - 6 - 4 = <<144-6-4=134>>134 #### 134 Carter is twice as tall as his 24” tall dog. Betty is 12” shorter than Carter. How tall is Betty in feet? How tall is Carter? ** Carter is twice as tall as 24” dog so he is 2*24 = <<2*24=48>>48” How tall is Betty? ** Betty is 12” shorter than Carter so Betty is 48-12 = <<48-12=36>>36” tall How tall is Betty in feet? ** 12" is the same as 1 foot so Betty is 36/12 = 3 feet tall #### 3 Legoland has 5 kangaroos for each koala. If Legoland has 180 kangaroos, how many koalas and kangaroos are there altogether? How many koalas are there? ** For every 5 kangaroos, there is one koala, meaning for the 180 kangaroos, there are 180/5 = <<180/5=36>>36 koalas. How many koalas and kangaroos are there altogether? ** Altogether, there are 36+180 = <<36+180=216>>216 koalas and kangaroos. #### 216 James has an old printer that crumples every seventh page and blurs the ink on every third page. If he prints 42 pages, how many are neither crumpled or blurred? How many pages are crumpled? ** First find the total number of pages that are crumpled: 42 pages / 7 = <<42/7=6>>6 pages How many pages are blurred? ** Then find the total number of pages that are blurred: 42 pages / 3 = <<42/3=14>>14 pages How many pages are both blurred and crumpled? ** Then find the number of pages that are both blurred and crumpled by finding how many numbers are less or equal to 42 and divisible by both 3 and 7: there are two, 21 and 42. How many pages are neither crumpled or blurred? ** Then subtract the number of crumpled and blurred pages from the total number of pages, and add the number of pages that were double-counted because they were both blurred and crumpled: 42 pages - 6 pages - 14 pages + 2 pages = <<42-6-14+2=24>>24 pages #### 24 Camden went swimming 16 times in March and Susannah went 24 times. If the number of times they went throughout the month was divided equally among 4 weeks, how many more times a week did Susannah swim than Camden? How many times did Camden go swimming in March? ** Camden went swimming 16/4 = <<16/4=4>>4 times a week How many times did Susannah go swimming in March? ** Susannah went swimming 24/4 = <<24/4=6>>6 times a week How many more times a week did Susannah swim than Camden? ** Susannah went 6 - 4 = <<6-4=2>>2 more times a week than Camden #### 2
