first, I need to turn my 10% in to a fraction:
10% ?
-------- = ______
100% 37.80
We want to find out what the question mark is ( which the question mark is equal to our answer)
First, I am going to multiply 10×37.80= 378
Then, I am going to divide 378 ÷ 100= 3.78
So my ?= 3.78
I hope this helped :)
