Answer = 1/2 or 0.5

Find the least common denominator or LCM of the two denominators:

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
