A pencil costs $0.60 plus sales tax. After sales tax the pencil
costs $0.63. What is the sales
tax rate?

5%

Step-by-step explanation:

To find the sales tax, find the difference between before and after tax:

0.63 - 0.60 = 0.03

To find the percentage, divide the difference by the cost of the product:

0.03/0.60 = 0.05

Multiply by 100 to find percent sales tax:

0.05 x 100 = 5%

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
