Question

a large serving of soup from Dayton's restaurant is 4/5 liters. The restaurant has 4 liters of soup leftover at the end of the night. How many servings of soup does the restaurant have left?

Answer 1

The restaurant has 5 servings left.
All you do is multiply 4 by 1.2

Answer 2

So what we have to do is divide the total of 4 liters by the fraction 4/5.

That gives us:

4 ÷ 4/5

Well before we go any further with the expression, we have to remember we can't actually divide by a fraction. So, instead, we multiply by the fraction's reciprocal. That gives us:

4 x 5/4

Now that we can do.

4 x 5/4 = 20/4, which we simplify to 5.

Dayton's restaurant has 5 servings of soup left. Hope I helped :)
