Question

(83, 2-80 1/6)×3/13​

Answer 1

Ответ:

Пошаговое объяснение:

(83,2 - 80 1/6) * 3/13 = 0,7

1) 83,2 - 80 1/6 = 83 2/10 - 80 1/6 = 83 1/5 - 80 1/6= 83 6/30 - 80 5/30 = 3 1/30

2) 3 1/30 * 3/13 = 91/30 * 3/13 = 7/10 = 0,7

Answer 2

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

P - Parentheses first E - Exponents (none in this case) MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

Let's simplify the expression step by step:

Step 1: Solve inside the parentheses 83, 2 - 80 1/6 = 83, 2 - (80 + 1/6) = 83, 2 - (480/6 + 1/6) = 83, 2 - (481/6)

Step 2: Convert the whole number to a fraction with the same denominator as 6 (common denominator): 83 = 83/1

Step 3: Subtract the fractions: 83/1 - 481/6

Step 4: Find a common denominator, which is 6: (683)/(61) - 481/6 = (498 - 481)/6

Step 5: Perform the subtraction: 17/6

Now we have (17/6) × 3/13:

Step 6: Multiply the fractions: (17/6) × 3/13 = (173)/(613) = 51/78

The final result of the expression is 51/78, which can be further simplified to 17/26 if needed.
