Answer: Lydia's answer is correct.
Explanation:
The solution used by Lydia is:
4/5 × 10 = 4 × 1/5 × 10
= 4 × 10/5
= 4 × 2
= 8
The above solution by Lydia is correct.
Given the question, 4/5 × 10, this will be:
= 4/5 × 10/1
Let's multiply the numerator first, this will be: = 4 × 10 = 40
The denominator will be: = 5 × 1 = 5
Therefore, 4/5 × 10/1 = 40/5
Now when we divide 40 by 5, we will get 8. Therefore Lydia is correct.
