Question

0,5×(1 1/2+2 2/3-1 3/4)-1 1/24=?

Answer 1

Ответ:

1/6

Пошаговое объяснение:

1) 1 3/6 + 2 4/6 = 4 1/6

2) 4 4/24 - 1 18/24 = 2 5/12

3)0,5× 2 5/12 = 29/24

4)29/24 - 25/24 = 1/6

Пошаговое объяснение:

1 1/2+2 2/3-1 3/4=1 6\12+2 8\12-1 9\12=2 5\12

0.5*2 5\12=1\2*29\12=29\24=1 5\24

1 5\24-1 1\24=4\24=1\6

Answer 3

To solve this expression, we'll first convert all the mixed numbers to improper fractions and then perform the operations step by step.

Step 1: Convert mixed numbers to improper fractions 1 1/2 = (21 + 1)/2 = 3/2 2 2/3 = (32 + 2)/3 = 8/3 1 3/4 = (41 + 3)/4 = 7/4 1 1/24 = (241 + 1)/24 = 25/24

Step 2: Perform the operations 0.5 * (3/2 + 8/3 - 7/4) - 25/24

Step 3: Find the common denominator for the fractions The common denominator for 2, 3, and 4 is 12.

Step 4: Convert all fractions to the common denominator 0.5 * [(6/12) + (32/12) - (21/12)] - 25/24

Step 5: Add and subtract the fractions inside the parentheses 0.5 * (17/12) - 25/24

Step 6: Distribute the multiplication (1/2) * (17/12) - 25/24

Step 7: Multiply the fractions (17/24) - 25/24

Step 8: Combine the fractions (17 - 25) / 24 = -8/24

Step 9: Simplify the fraction -8/24 = -1/3

So, the result of the expression is -1/3.
