Answer:
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%
Answer: 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
