Answer 2

Answer:

Solution :-

1) $\Longrightarrow$ $3 \times \dfrac{5}{8}$

$\Rightarrow$ $\dfrac{15}{8}$

$\Rightarrow$ $1.875$

2) $\longrightarrow$ $7 \times \dfrac{4}{15}$

$\Rightarrow$ $\dfrac{28}{15}$

$\Rightarrow$ $1.866$

3) $\Longrightarrow$ $\dfrac{3}{10} \times \dfrac{2}{5}$

$\Rightarrow$ $\cancel{\dfrac{6}{50}}$

$\Rightarrow$ $\dfrac{3}{25}$

4) $\longrightarrow$ $6 \times \dfrac{4}{3}$

$\rightarrow$ $\cancel{\dfrac{24}{3}}$

$\rightarrow$ $8$

5) $\Longrightarrow$ $\dfrac{35}{3} \times \dfrac{2}{15}$

$\Rightarrow$ $\cancel{\dfrac{70}{45}}$

$\Rightarrow$$\dfrac{14}{9}$

$\Rightarrow$ $1.555$

6) $\longrightarrow$ $\dfrac{1}{8} \times \dfrac{2}{15}$

$\rightarrow$ $\cancel{\dfrac{2}{120}}$

$\rightarrow$ $\dfrac{1}{60}$

7) $\Longrightarrow$ $\dfrac{3}{2} \times \dfrac{8}{5}$

$\Rightarrow$ $\cancel{\dfrac{24}{10}}$

$\Rightarrow$ $\dfrac{12}{5}$

$\Rightarrow$ $2.4$

8) $\longrightarrow$ $\dfrac{42}{3} \times \dfrac{51}{6}$

$\rightarrow$ $\cancel{\dfrac{2142}{18}}$

$\rightarrow$ $119$

9) $\Longrightarrow$ $\dfrac{52}{4} \times \dfrac{23}{2}$

$\Rightarrow$ $\cancel{\dfrac{1196}{8}}$

$\Rightarrow$ $\dfrac{299}{2}$

$\Rightarrow$ $149.5$
