sobtract 9 2/4 from 20 4/5​

Sagot :

Answer:

To subtract mixed numbers, we need to convert them to improper fractions first.

Convert mixed numbers to improper fractions:

* 20 4/5 = (20 * 5 + 4) / 5 = 104/5

* 9 2/4 = (9 * 4 + 2) / 4 = 38/4

Find a common denominator:

The least common multiple of 5 and 4 is 20.

* 104/5 = (104 * 4) / (5 * 4) = 416/20

* 38/4 = (38 * 5) / (4 * 5) = 190/20

Subtract the fractions:

416/20 - 190/20 = 226/20

Simplify the result:

226/20 = 11 3/10

So, 20 4/5 - 9 2/4 = 11 3/10
