Question

Fractions:-
(ii) $\frac{9}{5}-\frac{6}{7}+\frac{3}{2}-\frac{5}{4}.$

Answer 1

$\frac{9}{5}-\frac{6}{7}+\frac{3}{2}-\frac{5}{4}$

$=\frac{9\times 7}{5\times 7}-\frac{6\times 5}{7\times 5}+\frac{3\times 2}{2\times 2}-\frac{5}{4}$

$=\frac{63-30}{35}+\frac{6-5}{4}$

$\frac{33}{35}+\frac{1}{4}=\frac{33\times 4}{35\times 4}+\frac{1\times 35}{4\times 35}$

$=\frac{132+35}{140}=\frac{167}{140}$
