If 2 over 5 tons of concrete covers 5 over 6 of a wall, how many tons of concrete are required to cover the entire wall?

Dominik [7]

Answer:

A. 12.25 tons

Step-by-step explanation:

We will let x represent the amount required to cover the entire wall.

We can divided 2/5 by 5/6 to solve for x

2/5 divided by 5/6=x

When you divide by a fraction, you can always multiply by the reciprocal (flipped number).

Our new equation is:

2/5·6/5=12/25
