Type the correct answer in each box. If necessary, use / for the fraction bar(s).

this is my best guess

3.75 and 0.5

Answers:

a*b = 1/2

a/b = 8/9

Explanation:

The horizontal bar over the 6 means the 6 goes on forever

So we have a = 0.66666... which converts to the fraction a = 2/3

The b = 0.75 converts to b = 3/4

We can then say

a*b = (2/3)*(3/4)

a*b = (2*3)/(3*4)

a*b = 6/12

a*b = 1/2

and

a/b = (2/3) divide by (3/4)

a/b = (2/3)*(4/3)

a/b = (2*4)/(3*3)

a/b = 8/9

Note how I flipped the second fraction when I changed from a division to a multiplication.

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
