Question

( 6 - 9 3/5 ) × (1 2/3) - 12 ÷ ( - 3/4 + 1/8 )

Answer 1

1) 6 - 9 целых 3/5 = -3 целых 3/5
2) -3/4 + 1/8 = (-6+1)/8 = -5/8
3) -3 целых 3/5 * 1 целых 2/3 = -18/5 * 5/3 = -6
4) -6 - 12 = -18
5) -18 : - 5/8 = 18 * 8/5 = 28 целых 4/5

Answer 2

Let's break down the expression step by step:

Step 1: Simplify the expression inside the parentheses: 6 - 9 3/5 = 6 - (9 + 3/5) = 6 - (45/5 + 3/5) = 6 - 48/5 = (30/5) - (48/5) = -18/5

Step 2: Simplify the expression inside the second parentheses: -3/4 + 1/8 = -6/8 + 1/8 = -5/8

Step 3: Calculate the division and addition: 12 ÷ (-5/8) = 12 * (-8/5) = -96/5

Step 4: Multiply the results from Step 1 and Step 3: (-18/5) × (1 2/3) = (-18/5) × (5/3) = -18/3 = -6

Step 5: Subtract the results from Step 4 and Step 3: -6 - (-96/5) = -6 + (96/5) = (-30/5) + (96/5) = 66/5

Therefore, the final result is 66/5, which can also be expressed as a mixed number as 13 1/5.
