it takes one fourth of a gallon of paint covers one fifth of a car how much paint covers the whole car

Komok [63]

Answer:

The volume of paint that covers the whole car is $1\frac{1}{4}$ gallons or one and a quarter gallons.

Step-by-step explanation:

Let the volume of paint required to cover whole car be 'x'.

Given:

Volume of paint to cover one-fifth of a car = one-fourth of a gallon.

We use unitary method to determine the volume of paint required.

∵ One-fifth of a car requires paint = $\frac{1}{4}\ gal$

∴ Whole volume of car requires paint = $\frac{\frac{1}{4}}{\frac{1}{5}}$

$=\frac{1}{4}\times \frac{5}{1}\\=\frac{5}{4}\\=1\frac{1}{4}\ gal$

Therefore, the volume of paint that covers the whole car is $1\frac{1}{4}$ gallons or one and a quarter gallons.
