Question

A city's sales tax is 0.07 write this decimal as a fraction and tell how many cents of tax are on each dollar

Answer 1

as a fraction it is 7/100 and it would be 7 cents for each dollar. it is $1x.07

Answer 2

we know that

To convert the decimal as fraction in this problem, multiply and divide by one hundred

`0.07=0.07*(100)/(100)=(0.07*100)/(100)=(7)/(100)`

therefore

the answer Part a) is

the decimal as fraction is equal to
`(7)/(100)`

Part b)

we know that

`1` dollar is equal to
`100` cents

`1` cent is equal to
`0.01` dollars

the tax is equal to
`0.07` dollars

so

by proportion

`(100)/(1) (cents)/(dollar)=(x)/(0.07) (cents)/(dollars)\\ \\x=100*0.7\\ \\x=7\ cents`

the tax is equal to
`7` cents

therefore

the answer part b) is

There are
`7` cents of tax in each dollar
