Question

3 4/15+ y =7 11/15 ​

Answer 1

Ответ:

y= 4 7/15

Пошаговое объяснение:

3 4/15+ y = 7 11/15

49/15+y=116/15

y=116/15 -49/15

y=67/15

y=4 7/15

Answer 2

To solve the equation, let's simplify the fractions and isolate the variable "y".

First, let's convert the mixed numbers to improper fractions:

3 4/15 = (3 * 15 + 4) / 15 = 49/15

7 11/15 = (7 * 15 + 11) / 15 = 116/15

Now, the equation becomes:

49/15 + y = 116/15

To combine the fractions, we need a common denominator, which is 15 in this case. We can rewrite the equation as:

(49 + 15y) / 15 = 116/15

Now, we can cross-multiply to eliminate the denominators:

15 * (49 + 15y) = 15 * 116

735 + 225y = 1740

Next, let's isolate the variable by subtracting 735 from both sides:

735 + 225y - 735 = 1740 - 735

225y = 1005

Finally, divide both sides by 225 to solve for y:

y = 1005 / 225

Simplifying the division, we have:

y = 4.4667 (rounded to four decimal places)

Therefore, the solution to the equation 3 4/15 + y = 7 11/15 is y ≈ 4.4667.
