Find the equivalent fraction pairs from the following fractions.

$$\frac{2}{5}$$,$$\frac{8}{11}$$, $$\frac{42}{63}$$, $$\frac{57}{63}$$, $$\frac{48}{120}$$, $$\frac{2}{3}$$

Equate every fraction with other remaining fractions one by one

If the product of numerator of one and denominator of other is equal to product of denominator of one and numerator of the other than that pair is said to be equivalent

Lets take fraction $$\frac{2}{5}$$ and$$\frac{48}{120}$$

2×120 = 5 × 48

240 = 240

 So, $$\frac{2}{5}$$ and$$\frac{48}{120}$$ are equivalent

Similarly

$$\frac{42}{63}$$ and$$\frac{2}{3}$$ are equivqlent
