There are six chairs in each row in a church. If there are 20 rows of chairs in the church, and each chair holds five people, calculate the number of people who have to sit in the chairs for the church to be full.

How many chairs are there in the church? ** If there are six chairs in each row in the church, the total number of chairs in the church is 6*20 =

<<6*20=120>>120 How many people must sit in the chairs for the church to be full? ** Since each chair holds 5 people, 5*120 = <<5*120=600>>600 people must sit in all of the chairs for the church to be full. #### 600 Tim gets 6 hours of sleep 2 days in a row. To make up for it he sleeps 10 hours the next 2 days. How much sleep did he get? How many hours did Tim get the first 2 days? ** He got 2*6=<<2*6=12>>12 hours the first 2 days. How many hours did Tim get the next 2 days? ** The next 2 days he gets 2*10=<<2*10=20>>20 hours. How many hours did Tim get? ** So he got 12+20=<<12+20=32>>32 hours. #### 32 Jeanne wants to ride the Ferris wheel, the roller coaster, and the bumper cars. The Ferris wheel costs 5 tickets, the roller coaster costs 4 tickets and the bumper cars cost 4 tickets. Jeanne has 5 tickets. How many more tickets should Jeanne buy? How many tickets are needed? ** The total number of tickets needed is 5 tickets + 4 tickets + 4 tickets = <<5+4+4=13>>13 tickets. How many more tickets should Jeanne buy? ** Jeanne needs 13 tickets - 5 tickets = <<13-5=8>>8 tickets. #### 8 Forty percent of the students have elected to learn from home during the pandemic. The remaining students are divided into two equal groups, only one of which is physically in school on any day. What percent of students are present in school? What percent of students are remaining? ** 100-40=<<100-40=60>>60 percent of students are remaining. What percent of students are present in school? ** 60/2=<<60/2=30>>30 percent are present in school. #### 30 Sam, Sid, and Steve brought popsicle sticks for their group activity in their Art class. Sam has thrice as many as Sid, and Sid has twice as many as Steve. If Steve has 12 popsicle sticks, how many popsicle sticks can they use for their Art class activity? How many popsicle sticks does Sid have? ** Sid has 12 x 2 = <<12*2=24>>24 sticks. How many popsicle sticks does Sam have? ** Sam has 24 x 3 = <<24*3=72>>72 sticks. How many popsicle sticks do they have? ** Thus, they have 24 + 72 + 12 = <<24+72+12=108>>108 popsicle sticks. #### 108 John buys 1000 balloons. Each balloon holds 10 liters of air. If he buys 500-liter tanks of gas, how many tanks does he need to buy to fill all the balloons? How many liters of gas does John need? ** He needs 1000*10=<<1000*10=10000>>10000 liters of gas How many tanks does John need? ** So he needs 10000/500=<<10000/500=20>>20 tanks #### 20 Nadia walked 18 kilometers, which was twice as far as Hannah walked. How many kilometers did the two girls walk in total? How far did Hannah walk? ** Hannah = (1/2) 18 = 9 How far did Hannah and Nadia walk? ** 9 + 18 = <<9+18=27>>27 km How many kilometers did the two girls walk in total? ** Together they walked 27 kilometers. #### 27 Eric has 20 marbles. He has 12 white marbles, 6 blue marbles, and the rest are green marbles. How many green marbles does Eric have? How many white and blue marbles does Eric have? ** Eric has a total of 12 + 6 = <<12+6=18>>18 white and blue marbles. How many green marbles does Eric have? ** Thus, he has 20 - 18 = <<20-18=2>>2 green marbles. #### 2 Lana and her friends go to a theater on the weekend to watch a new play Joan told them was live. When they arrived, Lana saw 100 cars in the front parking lot. She saw two times more vehicles at the back than there were in the front parking lot. If the total number of cars at the end of the play was 700, how many more cars packed into the parking lot during the play? How many cars were in the back parking lot? ** The number of cars in the back parking lot was 100*2 = <<100*2=200>>200 times more than those in the front parking lot. How many cars were in the back parking lot? ** There were 200+100 = <<200+100=300>>300 cars in the back parking lot. How many cars were present before the play began? ** A total of 300+100 = <<300+100=400>>400 cars were present before the play began How many cars parked in the theater during the play? ** The total number of cars that parked in the theater during the play is 700-400 = <<700-400=300>>300 cars #### 300 If a solver flips a coin 211 times and gets a head on 65 of the flips, how many more tails than heads did he get? How many tails did the solver get? ** If the solver got a head in 65 of the 211 flips, he got 211-65 =<<211-65=146>>146 tails How many more tails than heads did the solver get? ** The number of tails than he got more than head is 146-65=<<146-65=81>>81 #### 81
