If 90 percent of a is 44, what is 30 percent of 3a?

1 answer:

3 0

90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...

0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded

what is 30% of 3a.....and we know that "a" is 48.89...

0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer

Answer:

12/12

Step-by-step explanation:

I would say simply perform the division already indicated.

(16 in)/(12 h) = 16/12 in/h = 4/3 in/h

Alternatively, divide the given rate by 1. The form 12/12 gives you the same thing as above:

(16 in)/(12 h)/(12/12) = (16/12) in/h = 4/3 in/h
