Answer 1

1/5 (5) = 5/5, or 1 cup of blue paint

1/3 (5) = 3/5, or 0.6 cup of yellow paint.

Answer 2

Answer:

$\dfrac{5}{3}$ cups

Step-by-step explanation:

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

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

                                                               = 5:3

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

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

$\Rightarrow \dfrac{1}{3}\div\dfrac{1}{5}$

$\Rightarrow \dfrac{5}{3}$

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