If five notebooks cost $5.25, how much would three notebooks cost?

Set it up as a ratio. $5.25/5 = $1.05 per notebook
Then solve your equation by multiplying the cost by 3. 3 * $1.05 = $3.15

The cost of **3 notebooks **is $4.5.
Given,
If five notebooks cost $5.25.
We need to find out how much would three notebooks cost .
How do find the cost of a required number of items from the cost of a number of items?
If we have,
3 apples cost $6.
3 apple = $6
To find the cost of 5 apples.
We will try to make the 3 apples into 5 apples.
Multiply 5/3 on both sides.
5/3 x 3 apples = 5/3 x $6
5 apples = $10
Find the cost of** 5 notebooks.**
= $5.25
Find the cost of three notebooks.
We have,
5 notebooks = $5.25
Multiply 3/5 on both sides.
3/5 x 5 notebooks = 3/5 x $5.25
3 notebooks = $4.5
Thus the cost of 3 notebooks is $4.5.
