Question

2/5 of 20 is 8. 3/5 of 20 is 12. complete the statement to explain how to find 3/5 of 20. first, i can find 1/5 of 20, which is 4. then i can find 3/5 of 20. that is? × 4.

Explanation:

Step1: Understand the fraction parts

We know that \(\frac{3}{5}\) means 3 parts of \(\frac{1}{5}\). Since \(\frac{1}{5}\) of 20 is 4, to find \(\frac{3}{5}\) of 20, we need to multiply the value of \(\frac{1}{5}\) of 20 (which is 4) by the number of \(\frac{1}{5}\) parts in \(\frac{3}{5}\). The number of \(\frac{1}{5}\) parts in \(\frac{3}{5}\) is 3.

Step2: Determine the multiplier

So, to find \(\frac{3}{5}\) of 20, we do \(3\times4\) (because we have 3 parts of \(\frac{1}{5}\), each part being 4). So the missing number is 3.
