Lu is making a quilt that is 20 squares wide and has 18 rows the border of the quilt is made by using each toy design equally as often there are a total of 6 toy designs each square can hold 1 design how many of each design does she use for the border?

The correct answer is two designs are used 12 times each and other four designs are used for 13 times each.

Step-by-step explanation:

Width of the quilt Lu is making is 18 rows of 20 squares each.

Thus the perimeter of the quilt is 20 + 20 + 18 + 18 = 76.

We can also say there are 76 square as the boundary which are to be bordered with toy designs.

Each square can hold 1 design of toy and there are 6 different designs of toys.

Thus number of times each design is used = 12 .

Thus there are two designs used 12 times each and other four designs are used for 13 times each.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
