A container is 1/8 full of water. After 10 cups of water are added, the container is 3/4 full. What is the volume in cups?

Respuesta :

3/4 = 6/8

6/8 - 1/8 = 5/8

so 5/8 ............10 cups
     8/8.............? cups

(8/8) * 10
-------------- = 16 cups
    5/8 

answer is 16 cups

Volume of the container having water will be 16 cups.

 It has been given in the question,

  • Container is [tex]\frac{1}{8}[/tex] full of water.
  • Water added in the container = 10 cups
  • After addition of 10 cups container is [tex]\frac{3}{4}[/tex] full.

  Let the volume of a container = V cups

If this container is [tex]\frac{1}{8}[/tex] full, volume of the water in the container = [tex]\frac{V}{8}[/tex] cups

By adding 10 cups of water, volume of the water in the container = [tex](\frac{V}{8}+10)[/tex] cups

Since, after adding 10 cups of water container is [tex]\frac{3}{4}[/tex] full.

Therefore, volume of water in the container = [tex]\frac{3V}{4}[/tex] cups

And the equation representing the situation will be,

[tex]\frac{V}{8}+10=\frac{3V}{4}[/tex]

[tex]\frac{3V}{4}-\frac{V}{8}=10[/tex]

[tex]\frac{6V-V}{8}=10[/tex]

[tex]\frac{5V}{8}=10[/tex]

[tex]V=16[/tex] cups

   Therefore, volume of the container is 16 cups.
