To find a missing ratio, you can use equivalent ratios or cross-multiplication to solve for the unknown value.

Front

What does a scale factor of 5 indicate?

Back

A scale factor of 5 indicates an enlargement, meaning the new figure is 5 times larger than the original.

Front

What is the solution to the equation a = 7?

Back

The equation a = 7 has one solution: a = 7.

Front

If the scale factor is 4, how do you find the new measurement?

Back

Multiply the original measurement by the scale factor. For example, if the original measurement is 6 m, the new measurement is 6 m * 4 = 24 m.

Front

What is a proportion?
