Answer:
Write the formula for one measurement, then solve the formula for the different measurement you want to find and use this new formula to find that measurement.
Step-by-step explanation:
We can understand this through an example.
If we need to find the lenght of a rectangle whose width is 4 feet and whose perimeter is 28 feet, we can use a formula for one measurement to write a formula for a different measurement:
- We need to write the formula for the perimeter of a rectangle:
Where "l" is the lenght and "w" is the width.
- Since we know the width and the perimeter of the rectangle and we need to find the lenght, we can solve for "l":
Now we get a new formula for calculate a differente measurement (the lenght of the rectangle).
- Substituting values, we get:
The fraction of medium sized shirt is .
Step-by-step explanation:
Given,
of the shirts are small sized.
of the shirts are large sized.
To find the fraction of medium sized.
Let us take total number of shirt = 1
Number of small sized shirt =c
Number of large sized shirt =
So,
Total number of large and small sized shirt =
=
Hence,
Number of medium sized shirt =
=
