Question

mcm FALL 2019-2020 TEST 5) Solve the following fraction:- (1 mark) 6) Solve the following fraction:- (1 mark) 2,2 5 3

Answer 1

5) we have $a\frac{b}{c}=\frac{(a*c)+b}{c}$

$5-3\frac{2}{3}=5-[\frac{3*3+2}{3}]$

$5-3\frac{2}{3}=5-\frac{11}{3}$

$5-3\frac{2}{3}=\frac{3*5-11}{3}$

$5-3\frac{2}{3}=\frac{15-11}{3}$

$5-3\frac{2}{3}=\frac{4}{3}$

6)we have

$\frac{a}{b}+\frac{c}{d}=\frac{(a*d)+(b*c)}{b*d}$

$\frac{2}{5}+\frac{2}{3}=\frac{(2*3)+(5*2)}{5*3}$

$\frac{2}{5}+\frac{2}{3}=\frac{6+10}{15}$

$\frac{2}{5}+\frac{2}{3}=\frac{16}{15}$
