Cody says that dividing a unit fraction by a whole number is the same as multiplying the unit fraction by a unit fraction with the whole number as the denominator. Which of the following supports Cody's reasoning?

A.1/4 ÷ 3 = 1/12 and 4 x 3 = 12
B.1/4 ÷ 3 = 1/2 and 1/4 x 1/3 = 1/12
C.1/4 ÷ 3 = 1/2 and 3 ÷ 1/4 = 12
D.3 ÷ 1/4 = 12 and 3 x 4 =12

x> 6

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
