Answer 2

To solve the equations, you need to isolate the variable (Y and y) on one side of the equation. Let's solve each equation step-by-step:

1. Y / 42 = 15 / 21

To solve for Y, cross-multiply:

21 * Y = 15 * 42

Now, divide both sides by 21:

Y = (15 * 42) / 21

Y = 30

So, the value of Y is 30.

2. 6.8 / y = 0.4 / 0.13

To solve for y, cross-multiply:

0.13 * 6.8 = 0.4 * y

Now, divide both sides by 0.4:

y = (0.13 * 6.8) / 0.4

y = 2.21

So, the value of y is approximately 2.21.
