Answer:
10 tacos costs $15.00
Step-by-step explanation:
I like to use ratio's to solve this type of problem. I will put cost over number of tacos.
$6.00 x dollars
-------- = --------------
4 tacos 10 tacos
Using cross products
6 * 10 = 4 * x
60 = 4x
Divide each side by 4
60/4 = 4x/4
15 =x
10 tacos costs $15.00
You can put it in a calculator, or do long division on a piece of paper. I would show you how to break it down step-by-step, but doing long division on here is complicated.
All you have to do is find the decimal of a fraction is to divide the numerator and the denominator.
In this case, divide 37 by 40 to get your decimal.
37 ÷ 40 = 0.925
So, the decimal form of 37/40 is 0.925.
