Answer 2

To simplify the given expression, let's break it down step by step:

Step 1: Simplify the expressions in the numerator and denominator separately.

Numerator: 0 + 25 + 2 = 27

Denominator: 2/15 + 5/7 ÷ 2/35 To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: 2/15 + 5/7 × 35/2 Now, find a common denominator: 2/15 + 25/7 To have a common denominator, convert 2/15 to a fraction with a denominator of 7: 2/15 × 7/7 = 14/105

Now, add the fractions together: 14/105 + 25/7 To add fractions with different denominators, find a common denominator, which is 105 × 7 = 735: (14/105) × (7/7) + (25/7) × (105/105) 98/735 + 2625/735 Now, add the fractions together: (98 + 2625) / 735 = 2723 / 735

Step 2: Simplify the second expression in the numerator and denominator separately.

Numerator: 20 ÷ 4 - 5/9 To divide whole numbers, we can simply perform the division: 20 ÷ 4 = 5

Now, subtract 5/9 from 5: 5 - 5/9 To subtract fractions with the same denominator, keep the denominator and subtract the numerators: (5 × 9 - 5) / 9 = 40 / 9

Denominator: 2/5 No further simplification is needed for the denominator.

Step 3: Divide the simplified expressions.

(2723 / 735) ÷ (40 / 9) To divide fractions, multiply the first fraction by the reciprocal of the second fraction: (2723 / 735) × (9 / 40) Now, multiply the numerators and denominators: (2723 × 9) / (735 × 40) = 24507 / 29400

The final result of the expression is 24507 / 29400. This fraction can be further simplified, but it is already in its reduced form.
