Question

(3 9/12+y)-4 9/12=1 7/12

Answer 1

(3 9/12+у)-4 9/12=1 7/12
3 9/12+у=6 4/12
у=2 7/12
Ответ: 2 целых 7/12.

Answer 2

(3 9/12+ у) - 4 9/12 = 1 7/12
3 9/12 + у = 1 7/12 + 4 9/12
3 9/12 + у= 5 16/12
у = 5 16/12 - 3 9/12
у = 2 7/12

Answer 3

Let's solve the equation step-by-step:

Given equation: (3 9/12 + y) - 4 9/12 = 1 7/12

Step 1: Simplify the mixed numbers on the left-hand side of the equation.

3 9/12 = 3 + 9/12 = 3 + 3/4 = 3 3/4

4 9/12 = 4 + 9/12 = 4 + 3/4 = 4 3/4

So, the equation becomes: (3 3/4 + y) - (4 3/4) = 1 7/12

Step 2: Perform the subtraction on the left-hand side of the equation.

(3 3/4 + y) - (4 3/4) = 1 7/12

To subtract mixed numbers, we need to borrow 1 from the whole number to the fraction part.

(3 3/4 + y) - (3 4/4 + 3/4) = 1 7/12

3 3/4 and 3 4/4 have the same whole number part, so we can directly subtract the fractions.

(3 3/4 + y) - (3 4/4 + 3/4) = (3 - 3) + (3/4 - 3/4) + y = 0 + 0 + y = y

So, the equation becomes: y = 1 7/12

Thus, the solution to the equation is y = 1 7/12.
