Describe how to create equivalent ratios

Since a ratio can also be written to look like a fraction, you can use your knowledge of creating equivalent fractions to this to create equivalent ratios. i.e: 5:10 can be written as 5/10, you can simplify it to 1/2 (1:2) or multiply it by 2/2 to get 10/20 (10:20).

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
