So, the ratio becomes
3:1
We need to find to make 1 gallon of pink paint ,
As we know that
![1\text{ gallon }= 128\text{ fluid ounces}](https://img.qammunity.org/2019/formulas/mathematics/high-school/t8z6sl2eirmea6qmuqb5cpz7tk6f54w5xt.png)
So,
Amount of red paint needed to make 1 gallon of pink shade is given by
![(3)/(4)* 128=(384)/(4)=96\ fluid\ ounces](https://img.qammunity.org/2019/formulas/mathematics/high-school/sw7q19i3ema122p4qy9zfpvna42e6ym8pg.png)
And,
Amount of white paint needed to make 1 gallon of white shade is given by
![(1)/(4)* 128=(128)/(4)=32\ fluid\ ounces](https://img.qammunity.org/2019/formulas/mathematics/high-school/ux8ig6s44twhuh5gqt0n3gagefcc0tj1ue.png)
Hence, 96 ounces of red paint and 32 ounces of white paint is needed to make 1 gallon of pink shade .
