Answer 2

To divide 2 and 17/20 by 1 and 9/10, we need to convert the mixed numbers to improper fractions and then perform the division.

First, let's convert the mixed numbers to improper fractions: 2 = 2/1 (since 2 divided by 1 is 2) 1 and 9/10 = (1 * 10 + 9)/10 = 19/10

Now we can perform the division: (2/1) ÷ (19/10)

When dividing fractions, we can multiply the first fraction by the reciprocal of the second fraction: (2/1) × (10/19)

Multiplying the numerators and denominators, we get: (2 × 10) / (1 × 19) = 20/19

Therefore, 2 and 17/20 divided by 1 and 9/10 is equal to 20/19.
