Ronda ate 2/5 of the pie. Connor ate .375 of the pie. How much did they eat combined? (Express your answer either as a fraction or decimal)

Miles is painting pumpkins for halloween. He has 3/4 of a gallon of paint. Each pumpkin needs .03 gallons to cover the pumpkin. How many pumpkins can he paint?

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!

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
