Answer 2

To solve the expression (1 24/25:1 2/5 - 5/6) • 4 2/7 + (28 - 27 6/7) • 53, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions: 1 24/25 = (25 * 1 + 24) / 25 = 49/25 1 2/5 = (5 * 1 + 2) / 5 = 7/5 4 2/7 = (7 * 4 + 2) / 7 = 30/7 27 6/7 = (7 * 27 + 6) / 7 = 193/7

Now we have: (49/25 : 7/5 - 5/6) • 30/7 + (28 - 193/7) • 53

Step 2: Perform the division and subtraction within the parentheses: (49/25 : 7/5 - 5/6) = (49/25 ÷ 7/5 - 5/6) = (49/25 * 5/7 - 5/6) = (245/175 - 25/30) = (49/35 - 5/6)

Step 3: Find a common denominator for the subtraction: The common denominator for 35 and 6 is 210.

(49/35 - 5/6) = (282/210 - 35/210) = (282 - 35) / 210 = 247/210

Now we have: (247/210) • 30/7 + (28 - 193/7) • 53

Step 4: Perform the remaining operations:

(247/210) • 30/7 = (247 * 30) / (210 * 7) = 7410/1470 = 5.04

(28 - 193/7) • 53 = (196 - 193/7) • 53 = (1375/7 - 193/7) • 53 = (1182/7) • 53 = (1182 * 53) / 7 = 69498/7 = 9928.29

Finally, we have: 5.04 + 9928.29 = 9933.33

Therefore, the value of the expression is approximately 9933.33.
