Question

Convert the given pair of unlike fractions in to like fractions.
$\frac{2}{5}and\frac{3}{7}$

Answer 1

To convert the unlike fraction in to like fraction, we have to make the denominators of both the fraction same.
$\frac{2}{5}\times \frac{7}{7}=\frac{14}{35}\frac{3}{7}\times \frac{5}{5}=\frac{15}{35}$
By multiplying with 7 and 5 we obtain the least common multiple 35 as denominator for both the fractions.

So, now the fractions,$\frac{14}{35}and\frac{15}{35}$ are like fractions.
