If 35% of a number is 21 and 90% of the same number is 54, find 55% of that number.

How do you do this on Delta Math?It is for 7th grade math.

Answer:

Explanation:

The number is 60:

Divide the amount and decimal of the percentage to be extracted

Case 1


(21)/(0.35) =60

Case 2


(54)/(0.9) =60

Now the 55% of this number is:


60(0.55)=33

Hope this helps
