Find the least common denominator or LCM of the two denominators:
LCM of 6 and 16 is 48
Next, find the equivalent fraction of both fractional numbers with denominator 48
For the 1st fraction, since 6 × 8 = 48,
5
6
=
5 × 8
6 × 8
40
48
Likewise, for the 2nd fraction, since 16 × 3 = 48,
15
16
15 × 3
16 × 3
45
Subtract the two like fractions:
-
40 - 45
-5
Answer:
15/16 - 5/6 = 31/48
Step-by-step explanation:
LCM of 6 and 80 is 240
Next, find the equivalent fraction of both fractional numbers with denominator 240
For the 1st fraction, since 6 × 40 = 240,
56 = 5 × 406 × 40 = 200240
Likewise, for the 2nd fraction, since 80 × 3 = 240,
1580 = 15 × 380 × 3 = 45240
200240 - 45240 = 200 - 45240 = 155240
After reducing the fraction, the answer is 31/48
