Answer 2

To solve this arithmetic expression, let's break it down step by step:

1. Convert the mixed numbers to improper fractions: 2 1/7 = (2 * 7 + 1) / 7 = 15/7 3 1/3 = (3 * 3 + 1) / 3 = 10/3

2. Divide the fractions: (15/7) : (3/28) = (15/7) * (28/3)

   To multiply fractions, multiply the numerators together and the denominators together: = (15 * 28) / (7 * 3) = 420/21 = 20

3. Now we have: 3 1/3 * (20/x) = 1.5

   To solve for x, we need to isolate x on one side of the equation. Let's simplify the left side first:

   3 1/3 * (20/x) = 1.5

   Convert 3 1/3 to an improper fraction: 3 1/3 = (3 * 3 + 1) / 3 = 10/3

   Rewrite the equation: (10/3) * (20/x) = 1.5

   Multiply the fractions: (10 * 20) / (3 * x) = 1.5

   Simplify the right side: 200 / (3 * x) = 1.5

4. Cross multiply and solve for x:

   200 = 1.5 * (3 * x)

   Multiply 1.5 by 3: 200 = 4.5 * x

   Divide both sides by 4.5 to solve for x: x = 200 / 4.5 x ≈ 44.44

Therefore, the value of x is approximately 44.44.
