At a party. andy and april shared a cherry pie. andy ate 2/5 of the pie and april ate 1/3 of the pie. what fraction of the pie did they eat altogether

the fraction of the cherry pie that they ate altogether is 11/15

Step-by-step explanation:

Let x represent the total size of the cherry pie that Andy and April shared.

Andy ate 2/5 of the pie. This means that the total amount of cherry pie that Andy ate is 2/5 × x = 2x/5

April ate 1/3 of the pie. This means that the total amount of cherry pie that April ate is 1/3 × x = x/3

The amount of the cherry pie eaten by both Andy and April would be

2x/5 + x/3 = 11x/15

Therefore, the fraction of the cherry pie that they ate altogether would be

(11x/15)/x = 11/15

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
