Nana76 [90]

Answer:

$\frac{5}{3}$ cups

Step-by-step explanation:

Jacob mixes $\frac{1}{3}$ cup of yellow paint for every $\frac{1}{5}$ cup of blue paint to make green paint.

The ratio of yellow paint to blue paint = $\frac{1}{3} : \frac{1}{5}$

= 5:3

$\frac{1}{5}$ cup of blue paint = $\frac{1}{3}$ cup of yellow paint

1 cup of blue paint = $\frac{1}{3}$ ÷ $\frac{1}{5}$ cup of yellow paint

⇒ $\frac{1}{3}$ ÷ $\frac{1}{5}$

⇒ $\frac{5}{3}$

Hence, For 1 cup of blue paint needed $\frac{5}{3}$ cups of yellow paint.
