30 subtract 21 1/5=?

Answer 1

To subtract 21 1/5 from 30, we need to convert both numbers into improper fractions.

30 = 30/1

21 1/5 = (21 × 5 + 1) / 5 = 106/5

Now we can subtract:

30/1 - 106/5

To subtract fractions, we need a common denominator, which in this case is 5.

(30 × 5)/5 - 106/5

150/5 - 106/5

(150 - 106) / 5

44/5

Thus, 30 - 21 1/5 = 44/5.
