The proportion 15 over 3 equals y over 7 , which number is equal to y in the proportion?

The equation is:

15/3 = y/7

To solve for y, first cross multiply:

15* 7 = 3 *y

Simplify:

105 = 3y

Divide both sides by 3:

y = 105/3

y = 35

For this case we have the following proportion:

We must find the value of "y".

We look for the value of "y" of the expression multiplying by 7 on both sides of the expression:

Finally, we have the value of "y" in the expression is 35

move it to the other side

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.
