Answer this question:A rectangle has a length of 40 meters and a width of 20 meters. A similar smaller rectangle has half the length and width of the big rectangle. What's the area of the smaller rectangle?
The length of the smaller rectangle is 1 / 2 * 40 = 20 meters. The width of the smaller rectangle is 1 / 2 * 20 = 10 meters. Since the area of a rectangle is found by multiplying the length times the width, the total area of the smaller rectangle is 20 * 10 = 200 meters square.
The answer is 200.

Answer this question:Samantha sleeps an average of 8 hours a night. Her baby sister sleeps 2.5 times as much as Samantha does. Because her father is so tired from watching the baby, for every hour the baby sleeps, he sleeps 30 minutes. How many hours does her father sleep in a week?
The baby sleeps 20 hours a day because 2.5 x 8 = 20. The baby sleeps 2 times as much as the father because 60 / 30 = 2. The father sleeps 10 hours a night because 20 / 2 = 10. The father sleeps for 70 hours a week because 7 x 10 = 70.
The answer is 70.

Answer this question:If Jenna has twice as much money in her bank account as Phil does, and Phil has one-third the amount of money that Bob has in his account, and Bob has $60 in his account, how much less money does Jenna have in her account than Bob?
If Phil has one - third of the amount that Bob does, that means he has $60 / 3 = $20 in his account. Since Jenna has twice as much money as Phil, that means she has $20 * 2 = 40 in her account. Since Bob has $60 in his account, that means he has $60 - $40 = $20 more than Jenna.
The answer is 20.
