Answer 2

The unknown number is 60.

Step-by-step explanation:

It is given that one-fifth of a number subtracted from two-thirds of it gives 28.

Let x be the unknown number.

$\dfrac{2}{3}x-\dfrac{1}{5}x=28$

Taking LCM on left side we get

$\dfrac{10x-3x}{15}=28$

$\dfrac{7x}{15}=28$

Multiply both sides.

$7x=28\times 15$

Divide both sides by 7.

$x=\dfrac{28\times 15}{7}$

$x=4\times 15$

$x=60$

Therefore, the unknown number is 60.
