Question

What percent of 84 is 126?
1) 102
2) 120
3) 150
4) 175

Answer 1

126/84=1.5
1.5 x 100 = 150%

Answer 2

To find the percentage, set up a proportion using the formula part/whole = percent/100. Cross-multiply and solve for the unknown percent. Option 3) is correct answer.

Step-by-step explanation:

To find the percentage, we can set up a proportion using the formula:

part/whole = percent/100

In this case, the part is 126, the whole is 84, and the percent is unknown. Therefore, we have:

126/84 = percent/100

Next, we can cross-multiply and solve for the unknown percent:

126 * 100 = 84 * percent

12,600 = 84 * percent

Dividing both sides of the equation by 84, we get:

percent = 12,600/84

percent ≈ 150

Therefore, 126 is approximately 150% of 84. Therefore the option 3) is correct answer
