A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint. How many pints of yellow paint will be needed i

katrin2010 [14]

Answer:

$1\frac{7}{8}$

Step-by-step explanation:

Given:

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint.

Question asked:

How many pints of yellow paint will be needed if the mixture contains one pint of blue paint ?

Solution:

We will easily find quantity of yellow paint, will be needed in the mixture, contains one pint of blue paint by using unitary method:

By using $\frac{2}{5} \ pint$ blue paint, yellow paint requires = $\frac{3}{4} \ pint$

By using 1 pint blue paint, yellow paint requires = $\frac{3}{4} \div\frac{2}{5} \\$

$=\frac{3}{4} \times\frac{5}{2} \\\\ =\frac{15}{8} \\\\ =1\frac{7}{8} \ pint$

Thus, $1\frac{7}{8}$ pint yellow paint requires in the mixture with one pint of blue paint.
