Ответ: 7 7/24

Пошаговое объяснение:

(20-17 3/4)+ (10 2/3- 5 5/8)=​7 7/24

1) 20-17 3/4= 2 1/4

2) 10 2/3- 5 5/8=​10 16/24- 5 15/24=5 1/24

3)2 1/4+ 5 1/24= 2 6/24 +5 1/24=7 7/24

Answer 3

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

Step 1: Simplify the first set of parentheses: (20 - 17 3/4) To subtract a mixed number from a whole number, we need to convert the mixed number to an improper fraction: 17 3/4 = (4 * 17 + 3)/4 = 71/4

So, the expression becomes: (20 - 71/4)

Step 2: Simplify the second set of parentheses: (10 2/3 - 5 5/8) Again, convert the mixed numbers to improper fractions: 10 2/3 = (3 * 10 + 2)/3 = 32/3 5 5/8 = (8 * 5 + 5)/8 = 45/8

So, the expression becomes: (32/3 - 45/8)

Step 3: Find the common denominator for the fractions in the second set of parentheses. The common denominator for 3 and 8 is 24.

So, the expression becomes: (32/3 - 45/8) = (256/24 - 135/24)

Step 4: Subtract the fractions with the same denominator: (256/24 - 135/24) = (256 - 135)/24 = 121/24

Step 5: Add the results from Step 1 and Step 4: (20 - 71/4) + (121/24)

Step 6: Convert the mixed number (20 - 71/4) to an improper fraction: 20 = (4 * 20 + 0)/4 = 80/4

So, the expression becomes: (80/4) + (121/24)

Step 7: Find the common denominator for the fractions. The common denominator for 4 and 24 is 24.

So, the expression becomes: (80/4) + (121/24) = (480/24) + (121/24)

Step 8: Add the fractions with the same denominator: (480/24) + (121/24) = 601/24

Therefore, the final result is 601/24.
