Question

(5-3/4)÷(1 1/2-1/12)×(1 1/13+2 2/5+1/4)=​

Answer 1

Ответ:

Пошаговое объяснение:

1) 4 4/4-3/4= 4 1/4

2) 3/2-1/12= 18/12-1/12=17/12

3) 14/13+12/5= 70/65+156/65= 226/62= 113/ 31

4) 113/31+1/4 = 452/ 124+ 31/124 = 483/124

5) 17/4:17/2= 17/4×2/17=1/2

6) 1/2 × 483/124 =483/248= 1 235/248

Answer 3

Let's break down the expression step by step:

1. First, simplify the fractions:

   • 5 - 3/4 = 20/4 - 3/4 = 17/4
   • 1 1/2 - 1/12 = 2/2 - 1/12 = 1 - 1/12 = 11/12
   • 1 1/13 + 2 2/5 + 1/4 = 13/13 + 12/5 + 1/4 = 1 + 2.4 + 0.25 = 3.65

2. Now, the expression becomes: (17/4) ÷ (11/12) × 3.65

3. To divide fractions, invert and multiply: (17/4) ÷ (11/12) = (17/4) × (12/11)

4. Now, multiply the fractions: (17/4) × (12/11) = (17 * 12) / (4 * 11) = 204/44

5. Simplify the fraction: 204/44 = 51/11

6. Finally, multiply by 3.65: (51/11) × 3.65 = (51 * 3.65) / 11 = 186.15 / 11

Now, you can simplify further if necessary. The result is approximately: 186.15 / 11 ≈ 16.92
