Answer:

b is greater than a by 1/4 of a

Explanation:

The statement “The number a is less than the number b by 1/5 of b”

means “if we subtract one fifth of b from b itself we get a”

we write this mathematically like this :


a=b-(b)/(5)

_________


\rightarrow a = (5b-b)/(5) =(4b)/(5)


a=(4b)/(5) \Longrightarrow 5a=4b


5a=4b\Longrightarrow b=(5a)/(4)


\Longrightarrow b=(5a)/(4) =(4a+a)/(4)=(4a)/(4)+(a)/(4)=a+(a)/(4)
