Step-by-step explanation:

Jan and Jerome are mixing red paint with white paint to make pink paint, in the ratio of 4 parts red to 5 parts white. How many gallons of red paint should they mix with 1 gallon of white paint? Express your answer as a common fraction

How many gallons of red paint should they mix with 1 gallon of white paint?

Let parts be represented as x

Hence:

Red : white

4 : 5

4/5 = x/ 1

We cross Multiply

5x = 4

x = 4/5

x = 0.8 gallons of red paint or 4/5 gallons of red paint

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

this is answer of 144 cubic meters
