Question

Here is how Lydia found the product 4/5 x 10. Use the model given to show that Lydia's answer is correct.

Answer 1

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.
