Question

1. \\(\frac{2}{5} = \frac{}{10}\\)

Explanation:

Step1: Recall fraction equivalence rule

To find the missing numerator, we know that to convert the denominator from 5 to 10, we multiply by 2 (since \(5\times2 = 10\)). By the rule of equivalent fractions, we must also multiply the numerator by 2.

Step2: Calculate the missing numerator

The original numerator is 2, so we do \(2\times2 = 4\). So \(\frac{2}{5}=\frac{2\times2}{5\times2}=\frac{4}{10}\).
