Question

12 3/4* 4/17* 5 4/9 +(2/3- 5/18) *2 4/7​

Answer 1

Ответ:

17 17/51

Пошаговое объяснение: 2/3-5/18=7/18

7/18*2 4/7=1

12 3/4*4/17*5 4/9=833/51

833/51+1=17 17/51

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Given expression: 12 3/4 * 4/17 * 5 4/9 + (2/3 - 5/18) * 2 4/7

Step 1: Convert all mixed fractions to improper fractions. 12 3/4 = (12 * 4 + 3) / 4 = 51/4 5 4/9 = (5 * 9 + 4) / 9 = 49/9 2 4/7 = (2 * 7 + 4) / 7 = 18/7

Step 2: Perform the multiplication and division from left to right. (51/4) * (4/17) * (49/9) + ((2/3) - (5/18)) * (18/7)

Step 3: Calculate the values in the parentheses. (51/4) * (4/17) * (49/9) + ((2/3) - (5/18)) * (18/7) = (51/4) * (4/17) * (49/9) + (6/9 - 5/18) * (18/7) = (51/4) * (4/17) * (49/9) + (12/18 - 5/18) * (18/7) = (51/4) * (4/17) * (49/9) + (7/18) * (18/7)

Step 4: Continue with the multiplication and division. (51/4) * (4/17) * (49/9) + (7/18) * (18/7) = (51/4) * (4/17) * (49/9) + 1

Step 5: Calculate the remaining multiplication. (51/4) * (4/17) * (49/9) + 1 = (51 * 4 * 49) / (4 * 17 * 9) + 1 = 63204 / 612 + 1 = 103 + 1 = 104

So, the final result is 104.
