Question 1

Question 2

A recipe requires 2.5 cups of milk. If 1 cup equals 237 mL, approximately how many milliliters of milk are needed?

2.5 × 237 = 592.5 mL, which rounds to approximately 593 mL.

Question 3

In a class of 30 students, 18 are female and 12 are male. If 6 females and 4 males received A grades, what fraction of students who received A grades are female?

Accepted Answer

3/5

Answer

A total of 6 + 4 = 10 students received A grades, and 6 of them are female, so the fraction is 6/10 = 3/5.

Question 4

A pie chart shows that 35% of students prefer math, 25% prefer science, and 20% prefer English. What percentage prefer history?

Accepted Answer

20%

Answer

All percentages must sum to 100%, so history = 100% − 35% − 25% − 20% = 20%.
