Let’s solve each problem one by one. All of them involve finding “half” of a number — that means dividing the total by 2.

Problem 1: Wang Lei and 10 donuts
Wang Lei ate half of 10 donuts.
Half of 10 = 10 2 =
5
→ He ate
5 donuts.
---
Problem 2: Sara and 30 cookies
Sara ate half of 30 cookies.
Half of 30 = 30 ÷ 2 =
15
→ She ate
15 cookies.

Half of 20 = 20 ÷ 2 =
10
→ She ate
10 cookies.

Problem 4: Anand and 10 erasers
Anand gave away half, so he is left with the other half.
Half of 10 = 10 ÷ 2 =
5
→ He was left with
5 erasers.

Problem 5: Wang Lei and 14 donuts
Wang Lei ate half of 14 donuts.
Half of 14 = 14 2 =
7
→ He ate
7 donuts.

Problem 6: Sonia and 30 chocolates
(Note: The question says “How many chocolates did Sara eat?” but it should be Sonia — we’ll assume it’s a typo and answer for Sonia.)
Sonia ate half of 30 chocolates.
Half of 30 = 30 ÷ 2 =
15
→ She ate
15 chocolates.
