SAT Math Question for the week of 10/10/2021

What is 25% of 1% of 500% of 120?

Maps to Category 45 of my book.

 

Answer on 10/17/2021: Correct answer is 1.5.


Convert all the percentages to decimals and then multiply all the numbers. The order of the numbers during multiplication does not matter.


0.25 x 0.01 x 5 x 120 = 1.5


If you are not familiar with converting percent to decimal, check the Math Corner under Resources.

= 25/100 × 1/100 × 500/100 × 120

= 1500000/1000000

= 1.5

Answer is 1.5

You can avoid working with big numbers by converting percentages to decimal before multiplication.
