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?
1 answer:
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
