Equivalent Fractions Worksheets - 15 Worksheets Library - Free Printable

Let's solve each of the equivalent fractions step by step. The goal is to find missing numerators or denominators so that the fractions are equivalent (equal in value).

We'll use the concept:
If two fractions are equivalent, then their cross-products are equal, or we can multiply both numerator and denominator by the same number to get an equivalent fraction.

🔍 How to Check:

For example, check #1:
$\frac{2}{5} = \frac{4}{10}$ → $2 \times 10 = 20$, $5 \times 4 = 20$ → same → ✔️
Similarly, all others follow the same logic.

You can verify any fraction using cross-multiplication:
$a/b = c/d$ → $a \times d = b \times c$
