Which steps should be followed to use a scale drawing and a new scale to find the new length of a soccer field? 1 Add the numerator of the new scale to the old length to get the new length.

2 Subtract the new length from the old length to find the difference in lengths.

3 Write a proportion using the new scale as the first ratio. Set the first ratio equal to the ratio of the length of the original field compared to a variable that represents the new length of the field. Solve the proportion to find the new length of the field.

4 Write a ratio comparing the scale drawing length to the actual length of the field, and simplify.
