Given the expression;
9 1/8 = 2 4/5 + p
We are to find the value of p
First you will have to express the mixed fractions as improper fraction as shown;
9 1/8 = 2 4/5 + p
73/8 = 14/5 + p
Subtract 14/5 from both sides
73/8 - 14/5 = 14/5 + p - 14/5
73/8 - 14/5 = p
p = 73/8 - 14/5
Find the LCM
p = 5(73)-8(14)/40
p = (365-112)/40
p = 253/40
Express the answer as a mixed fraction;
p = + p - 14/5
73/8 - 14/5 = p
p = 73/8 - 14/5
