Answer:
1 17/40
Step-by-step explanation:
2 5/8 - 1 1/5
Find the LCD or the least common denominator of 5/8 and 1/5.
8(denominator) - 8, 16, 24, 32, 40
5(denominator) - 5, 10, 15, 20, 25, 30, 35, 40
40 is the LCD, therefore...
5/8
40(LCD) ÷ 8(denominator) = 5 x 5(numerator) = 25/40
1/5
40(LCD) ÷ 5(denominator) = 8 x 1(numerator) = 8/40
Change 5/8 into 25/40, and 1/5 into 8/40.
Therefore...
2 25/40 - 1 8/40
= 1 17/40 is the answer.
I hope my explanation helps. :>
