Answer 2

To solve the given equations, let's work on them one by one:

1. 2 2/5 : x = 48/75

First, convert the mixed number 2 2/5 to an improper fraction: 2 2/5 = (5 * 2 + 2) / 5 = 12/5

Now, we can rewrite the equation as: 12/5 : x = 48/75

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction: 12/5 * 75/48 = (12 * 75) / (5 * 48) = 900/240 = 45/12 = 15/4

Therefore, x = 15/4.

2. 17/38y = 6 5/19

First, convert the mixed number 6 5/19 to an improper fraction: 6 5/19 = (19 * 6 + 5) / 19 = 119/19

Now, we can rewrite the equation as: 17/38y = 119/19

To solve for y, we need to isolate it. Multiply both sides of the equation by the reciprocal of 17/38 to eliminate the fraction on the left side: (17/38) * (38/17) * y = (119/19) * (38/17) y = (119 * 38) / (19 * 17) y = 4522/323 y = 2261/161

Therefore, y = 2261/161.
