Answer = 1/2 or 0.5
Find the least common denominator or LCM of the two denominators:
LCM of 5 and 10 is 10
For the 1st fraction, since 5 × 2 = 10,
4/5= 4 × 2 Divided by 5 × 2 = 8/10
Likewise, for the 2nd fraction, since 10 × 1 = 10,
3/10 = 3 × 1 Divided By 10 × 1 = 3/10
Subtract the two fractions:
8/10 - 3/10 = 8 - 3 divided by 10 = 5/10
After reducing the fraction, the answer is
1/2
