Hope this helps!!

Answer:

She needs 16 drops of blue food coloring.

Step-by-step explanation:

We are given that,

Drops of yellow food coloring used = 3

Drops of blue food coloring used = 4

So, the ratio of yellow food coloring to the blue food coloring = [tex]\frac{3}{4}[/tex]

It is required to find the drops of blue food coloring if she uses 12 drops of yellow food coloring.

Let the drops of blue food coloring = x.

So, we have,

[tex]\frac{3}{4}=\frac{12}{x}[/tex]

i.e. [tex]x=\frac{12\times 4}{3}[/tex]

i.e. x = 4 × 4

i.e. x = 16

Thus, she needs 16 drops of blue food coloring.
