Answer:
182 1/3 lbs
MAY: weight = 170 2/3
Summer: gained 25 5/12
New weight : 170 2/3 + 25 5/12
Get a common denominator of 12
170 2/3 *4/4 + 25 5/12
170 8/12 + 25 5/12 = 195 13/12
The he lost 10 1/4 during the first week of fall practice
195 13/12 - 10 1/4
We need to get a common denominator of 12
195 13/12 - 10 1/4*3/3
195 13/12 - 10 3/12
185 10/12
The he lost another 3 1/2 pound during the second week
185 10/12 - 3 1/2
We need to get a common denominator of 12
185 10/12 - 3 1/2 * 6/6
185 10/12 - 3 6/12
182 4/12
Simplify the fraction
182 1/3 lbs
Hope this helps!
