Answer 2

To solve the equations, we need to find the value of 'x' in each case. Let's break down the two equations step by step:

1. Equation 1: 3/20 : 10/33 = 19

To solve this, we can first find the value of the left-hand side of the equation and then equate it to 19.

Step 1: Simplify the left-hand side of the equation: 3/20 : 10/33 = (3/20) ÷ (10/33)

Step 2: To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction: (3/20) * (33/10)

Step 3: Simplify the multiplication: (3 * 33) / (20 * 10) = 99 / 200

Now, the equation becomes: 99 / 200 = 19

However, the equation is not correct. It seems there might be an error in the given equation.

2. Equation 2: 4/5 : x - 15

To solve this equation, we need more information. The equation seems to be incomplete. There should be an expression on the right-hand side or an equation where this ratio is being used. Without additional information or context, we cannot determine the value of 'x'.

If you provide more details or clarify the equations, I'd be happy to help you solve them.
