Answer 2

Answer:  The number is 60

Step-by-step explanation:

We have to find a number whose $\dfrac{2}{3}$ is less than its $\dfrac{4}{5}$ by 8

Let the number be x

Therefore according to question

$\dfrac{2}{3}x+8= \dfrac{4}{5} x\\\\\Rightarrow \dfrac{2}{3}x- \dfrac{4}{5} x=-8\\\\\Rightarrow \dfrac{10x- 12x}{15} =-8\\\\\Rightarrow \dfrac{-2x}{15} =-8\\\\\Rightarrrow x= 60$

Hence, the number is 60
