Answer:

150

Explanation:

90% can be rewritten as 9/10.

We can represent the original number as the variable x and construct an equation that models the given situation.

$(9)/(10) \cdot x = 135$

Then, we can solve the equation for x by multiplying both sides by the reciprocal of 9/10, which is 10/9.

$(10)/(9)\left((9)/(10) \cdot x\right) = (135)\left((10)/(9)\right)$

$x = 10 \cdot (135)/(9)$

$x = 10\cdot 15$

x = 150
