Question

6/7 - 3/4 subtract fraction with unlike denominators

Answer 1

Substraction of fractions:

$\frac{a}{b}-\frac{d}{e}=\frac{a\cdot e-b\cdot d}{b\cdot e}$

For the given substraction:

$\frac{6}{7}-\frac{3}{4}=\frac{6\cdot4-7\cdot3}{7\cdot4}=\frac{24-21}{28}=\frac{3}{28}$

Then the result of the given substraction is 3/28
