Answer 2

To simplify the given expression, we'll first convert all the mixed fractions to improper fractions and then perform the operations. Here's the step-by-step calculation:

Step 1: Convert mixed fractions to improper fractions. 10 3/7 = (10 * 7 + 3)/7 = 73/7 25 8/15 = (25 * 15 + 8)/15 = 383/15 8 8/15 = (8 * 15 + 8)/15 = 128/15 10 3/7 = 73/7

Step 2: Perform the operations. 73/7 * 383/15 - 128/15 * 73/7

Step 3: Find the common denominator, which is 15 * 7 = 105.

(73/7) * (383/15) = (73 * 383) / (7 * 15) = 27859 / 105

(128/15) * (73/7) = (128 * 73) / (15 * 7) = 9344 / 105

Step 4: Subtract the second term from the first term.

(27859 / 105) - (9344 / 105) = (27859 - 9344) / 105 = 18515 / 105

Step 5: Simplify the fraction if possible. 18515 ÷ 105 = 176 remainder 65

So the final result is: 176 65/105

To simplify the fraction further, we can find the greatest common divisor (GCD) of 65 and 105, which is 5. Divide both the numerator and denominator by 5:

65 ÷ 5 = 13 105 ÷ 5 = 21

The final result is:

176 13/21
