Do the ratios 1/2 and 6/12 form a proportion

1 = 6

2 12

Cross multiply:

1 * 12 = 2 * 6

Simplifying

1 * 12 = 2 * 6

Multiply 1 * 12

12 = 2 * 6

Multiply 2 * 6

12 = 12

Add '-12' to each side of the equation.

12 + - 12 = 12 + - 12

Combine like terms: 12 + - 12 = 0

0 = 12 + - 12

Combine like terms: 12 + - 12 = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.
