Question

The container that holds the water for the football team is 3/10 full. After pouring in 7 gallons of water, it is 4/5 full. How many gallons can the container hold?

Answer 1

Step-by-step answer:

This is a problem involving subtraction of fractions.

To solve the problem, we find out the increase of the fraction of container and equate it to the amount of water added.  Then we find the amount of water contained in the whole container (fraction = 1)

7 gallons = 4/5 - 3/10 = 8/10 - 3/10 =5/10 = 1/2 container

therefore, multiply by two on both sides,

14 gallons = 1 container

So container can hold 14 gallons.

Answer 2

What is Volume ?

The volume of a 3D object is the amount of space it contains. A fish tank, for example, is three feet long, one foot wide, and two feet tall. To get the volume, multiply the length by the breadth by the height, which is 3x1x2, or six. As a result, the fish tank has a volume of 6 cubic feet.

How to solve?

Volume of cuboidal container- LBH

Given after poring 7 gallons tank is 4/5 full

Hence 7 gallon=4/5x

x=7*5/4=35/4gallon

Hence container can hold 35/4 gallon i.e=8.75gallon
