In a sale normal prices are reduced by 10% natalie bought a pair of shoes in the sale for £54
Nookie1986 [14]

Answer:

60

Step-by-step explanation:

Steps to solve "54 is 90 percent of what number?"

We have, 90% × x = 54

or,  

90/100  × x = 54

Multiplying both sides by 100 and dividing both sides by 90,

we have x = 54 ×  100/90  

x = 60

If you are using a calculator, simply enter 54×100÷90, which will give you the answer.
