For the first question, you know that Amy has 72 sweets in her bag, she keeps 1/4 of the 72 for herself, which is 72/4 = 18.
72 - 18 = 54. She will give 54 sweets and distribute them to her friends.
2. 150 people are on the train
150 x 2/5 or 60 people leave
150 - 60 = 90.
90 + 35 since 35 people get on the train again, 125.
There are 125 people on the train.
3. 4/7 • x = 48
84 dollars = x
4. 1/6 of 372 = 62
372 - 62 = 310.
310 - 62 = 248. There are 248 more red beads than blue beads.
5. Simply add up the fractions and say that 5/6 of total = 35, solve for total by dividing 5/6 fraction from 35.
