Answer 2

Answer:

Sum of $\tt4 \dfrac{3}{4} \: and \: 9 \dfrac{2}{5}$

$➜\tt4 \dfrac{3}{4} \: + \: 9 \dfrac{2}{5}$

$➜\tt \dfrac{19}{4} \: + \: \dfrac{47}{5}$

LCM = 4 × 5 = 20

$➜\tt \dfrac{19}{4} \times \dfrac{5}{5} = \dfrac{95}{20}$

$➜\tt \dfrac{47}{5} \times \dfrac{4}{4} = \dfrac{188}{20}$

$➜ \tt \dfrac{95}{20} + \dfrac{188}{20}$

$➜ \tt \dfrac{283}{20}$

$➜ \tt14 \dfrac{3}{20} \: or \: 14.15$

Hence, $\tt4 \dfrac{3}{4} \: + \: 9 \dfrac{2}{5}$ is $\tt14 \dfrac{3}{20} \: or \: 14.15$
