A square foot wall of space needs 1/8 quart of paint. Terrence has 7 quarts of paint, but uses 2 quarts to paint a pipe. How many square feet of wall can he paint with the rest of the paint

Respuesta :

Answer:

40 square feet.    

Step-by-step explanation:

We have been given that a square foot wall of space needs 1/8 quart of paint. Terrence has 7 quarts of paint, but uses 2 quarts to paint a pipe.

The amount of paint that left will be 5 quarts (7-2=5).

To find the area of wall that can be painted with the rest of paint, we will divide amount of left paint by the amount used to paint one square foot of wall.

[tex]\text{The number of square feet that can be painted with rest of paint}=5\div \frac{1}{8}[/tex]

Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.

[tex]\text{The number of square feet that can be painted with rest of paint}=5\times \frac{8}{1}[/tex]

[tex]\text{The number of square feet that can be painted with rest of paint}=5\times 8=40[/tex]

Therefore, 40 square feet of wall can be painted with the rest of the paint.
