You dont have to do all the questions atleast like two

the answer for number 1 is 72

Step-by-step explanation:

Assume the unknown value is 'Y'

18 = 25% x Y

18 = 25/100 x Y

Multiplying both sides by 100 and dividing both sides of the equation by 25 we will arrive at:

Y = 3 x 100/25

Y = 72%

18 is 25 percent of 72

If you want to use a calculator to check my answer just simply enter 18x100÷25 and you will get your answer which is 72
