Question

Cristiano has 42 apples in his bag and his brother has only 16. How many apples should Cristiano give his brother so they both have the same number of apples? ​

Answer 1

• Cristiano gave 13 apples to his brother.

Explanation:

We know that:

• Cristiano = 42 apples
• Cristiano's brother = 16 apples

Since Cristiano has more apples than his brother, Cristiano must give his apples to his brother. Let's name Cristiano as C and his brother as B.

• => C - x = B + x
• => 42 - x = 16 + x
• => 42 + 16 = x + x
• => 58 = 2x
• => x = 29

This means that when Cristiano has equal apples to his brother, they will have 29 apples.

• => 42 - 29 = Apples given by Cristiano.
• => 13 = Apples given by Cristiano

Hence, Cristiano gave 13 apples to his brother.

Answer 2

13

Explanation:

Total number of apples: 42 + 16 = 58

For each brother to have the same number of apples: 58/2 = 29 apples each

Therefore, to calculate the number of apples Cristiano has to give his brother, subtract 29 from the original number of 42 apples:

42 - 29 = 13
