Total weight:  3 1/3 lbs.  or  10/3 lbs.
Meat weight:  2  7/8  or    23/8 lbs.
Bone weight:  x

Equation:
x = 10/3 - 23/8

LCD (Least common denominator), listing method:
3 = 3, 6, 9, 12, 15, 18, 21, 24
8 = 8, 16, 24


Re-write the equation with similar fractions:
x = 10/3 - 23/8
x = 80/24  -  69/24
x = 11/24  

Final Answer:  The weight of the bone is 11/24  lbs.




11/24   +   69/24   = 10/3 lbs.
80/24  =  10/3
10/3 = 10/3   or 3  1/3


Lowest term of 80/24 = 10/3
(numerator)  80 
÷ 8 = 10     Divide by GCF = 8
(denominator)  24 ÷ 8 = 3   Divide by GCF = 8

hi Good morning. thnks again your answer. i have questions in no.3 problem about the weight. x=10/3-23/8 x=80/24-69/24 ×=11/24 ? how come 80/24-69/24 and the answer is 11/24 ?
Subtract the numerators 80-69 = 11.Then copy the denominator. The result is 11/24. In addition and subtraction of fractions, the fractions must be similar. Similar fractions have the same denominators. If the given data are not similar, they have to be converted to similar fractions. You must have prior knowledge of how to do it to be able to add or subtract dissimilar fractions.Add or subtract the numerators, copy the denominator because they fractions are similar, then reduce to lowest terms.
