Question

$$3/7+4/9$$

$\frac{55}{63}\approx 0.873015873$

Least common multiple of $7$ and $9$ is $63$. Convert $\frac{3}{7}$ and $\frac{4}{9}$ to fractions with denominator $63$.

$$\frac{27}{63}+\frac{28}{63}$$

Since $\frac{27}{63}$ and $\frac{28}{63}$ have the same denominator, add them by adding their numerators.

$$\frac{27+28}{63}$$

Add $27$ and $28$ to get $55$.

$$\frac{55}{63}$$

$\frac{5 \cdot 11}{3 ^ {2} \cdot 7} = 0.873015873015873$
