Frank and his mom got some fruit at the fruit stand yesterday. they bought 2 and 1 half pounds of peaches,7 eighths of a pound of raspberries, and 1 and 1 fourth pounds of apricots. how many pounds of fruit did they buy in all?

4 5/8 lbs or 37/8 lbs

Step-by-step explanation:

Peaches: 2 1/2 pounds

Raspberries: 7/8 pound

Apricots: 1 1/4 pounds

Since mixed fractions are used, first convert them to improper fractions.

P = 5/2

R = 7/8

A = 5/4

Now, find the least common denominator.

LCD = 16

P = 8(5/2) = 40/16

R = 2(7/8) = 14/16

A = 4(5/4) = 20/16

Add all the new fractions together.

(40/16) + (14/16) + (20/16) = 74/16

Simplify by factoring 2.

(74/16)/2 = 37/8

Either keep as improper or change to mixed number.

4 5/8 lbs

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
