Answer: 2/5 of the pie is .4 added to .375 equals .775 they ate all together.

3/4 is .75 gallon. To find how many pumpkins he can paint, divide .75÷ .03 = 25 pumpkins.

Step-by-step explanation:

To convert fractions to decimals, divide the numerator by the denominator. 7/8 = .875

To convert a decimal to a fraction, use the digits as the numerator and make the denominator a power of 10 with one place more than the numerator. Then reduce or simply. Examples:

.5 = 5/10 = 1/2

.75 = 75/100 = 3/4

.125 = 125/1000 = 1/8

I hope this helps you!
