Question

(12:3 3\5+2\3):1 1\2-1 1\3

Answer 1

В ответе получается 1 1/3

Answer 2

To solve the expression, let's break it down step by step:

Step 1: Simplify the addition and subtraction within the parentheses. 3/5 + 2/3 = (9/15) + (10/15) = 19/15

Step 2: Simplify the division outside the parentheses. (12:3) = 12/3 = 4

Step 3: Simplify the subtraction. 1 1/2 - 1 1/3 = (3/2) - (4/3)

To subtract fractions, we need a common denominator. The common denominator in this case is 6.

(3/2) = (3/2) * (3/3) = 9/6 (4/3) = (4/3) * (2/2) = 8/6

Subtracting these fractions, we get:

9/6 - 8/6 = 1/6

Step 4: Divide the result from step 1 by the result from step 3. (19/15) : (1/6)

Dividing fractions is the same as multiplying by the reciprocal of the divisor.

(19/15) * (6/1) = (19 * 6) / (15 * 1) = 114/15

Therefore, the final result is 114/15.
