Felice went on a diet. at the beginning of the diet, she weighed 131 3⁄4 pounds. two months later, she weighed 115 5⁄8 pounds. during the following month, she lost another 5 2⁄3 pounds. how much weight did felice lose in all?

Felice lost 21  19/24 pounds in all.

Step-by-step explanation:

Weight at the begining: W0=131 3/4 pounds

Weight two months later: W1=115 5/8 pounds

Felice lost in the first two months: L1=W0-W1

L1=(131 3/4 pounds)-(115 5/8 pounds)

L1=(131-115) (3/4-5/8) pounds

L1=16 (3/4)*(2/2)-5/8 pounds

L1=16 (3*2)/(4*2)-5/8 pounds

L1=16 6/8-5/8 pounds

L1=16 (6-5)/8 pounds

L1=16 1/8 pounds

During the following month she lost another 5 2/3 pounds:

L2=5 2/3 pounds

How much did Felice lose in all?

LT=?

LT=L1+L2

Replacing the known values:

LT=16 1/8 pounds + 5 2/3 pounds

LT=(16+5) (1/8+2/3) pounds

LT=21 (1/8)*(3/3)+(2/3)*(8/8) pounds

LT= 21 (1*3)/(8*3)+(2*8)/(3*8) pounds

LT=21 3/24+16/24 pounds

LT=21 (3+16)/24 pounds

LT=21  19/24 pounds

Felice lost 21  19/24 pounds in all.
