Question

A certain shade of pink is created by by adding 3 cups of red paint to 7 cups of white paint. How many cups of red paint should be added to 1 cup of white paint. Cups of white paint. Cups of red paint 1. ? 7. 3 And what is the Constant of Proportionality?

Answer 1

Answer:

→[ Certain shade=red paint+ white paint]

→3 cups of red paint=7 cups of white paint

Dividing both side by 7,we get

→ 1 cup of white paint=3/7 cups of white paint

So, 3/7 of a cup should be added to 1 cup of white paint to make certain kind of shape.

Cups of white paint: Cups of red paint= 1. : $\frac{7}{3}=\frac{3}{7}$

k=$\frac{3}{7}$ is constant of proportionality.

Answer 2

Answer:

0.4286 cups or $\frac{3}{7}$ of red paint should be added to 1 cup of white paint.

$\frac{3}{7}$ is the Constant of Proportionality.

Step-by-step explanation:

For a certain pink shades , 3 cups of red paint requires 7 cups of white paints.

So, according to information, 7 cups of white paints need to 3 cups of red paints.

So, 1 cup of white paint will need :$\frac{3}{7}=0.4286 cups$ of red paint.

0.4286 cups or $\frac{3}{7}$ of red paint should be added to 1 cup of white paint.

Cups of red paint ∝ Cups of white paint

(Cups of red paint) = k × (Cups of whitepaint)

k = Constant of Proportionality

$k=\frac{\text{Cups of red paint}}{\text{Cups of white paint}}=\frac{3}{7}$

$\frac{3}{7}$ is the Constant of Proportionality.
