Dani uses the table to help her convert measurements when she is sewing. Describe the relationship between the number of feet and the number of yards.

Write an expression for the number of yards in f feet.

Find the number of yards in 63 feet.

1Yarda = 3 feet

y = (1/3) f

y = 21

Step-by-step explanation:

The first thing we should do is see what relationship we have:

Table is feet to yards 3-1

a. Describe the relationship between the number of feet and the number of yards

That is to say:

1Yarda = 3 feet

b. Write an expression for the number of yards in f feet

Let

y = Yard

f = feet

We have the following expression for the conversion:

y = (1/3) f

c. Find the number of yards in 63 feet

For this case we must substitute in the expression found the value of f = 63.

y = (1/3) f

y = (1/3) (63)

y = 21

(pls mark me the Brainliest)

There are 3 feet per yard

# of yards = 3f

189 feet

Step-by-step explanation:

f = feet

y = yard

First Question: Dividing the # of feet by # of yards for one column will always equal 3. So there are 3 feet per 1 yard

Examples: 3/1=3, 6/2=3, 9/3=3 ...

Second Question: To find the number of yards, divide the number of feet by 3. In other words, f/3=y

Third Question: Using the expression f/3=y, there are 21 yards in 63 feet

Prosses:

f/3=y

63/3 = y

21 = y
