I need this by tomorrow morning

Question

I had $6 to pay for part of lunch. My friend had enough money to pay the other part or 3/5 of the bill. What is the total bill?

Answer 1

is this the right answer:
My friend paid 9 dollars and the total bill is 15?

Could you also tell me if the answer to the following is 16?

If 12 counters are 3/4 of a set, what is the whole set?

Answer 2

You could set it up this way, with x equal to the total bill:

2/5 x = 6
x = 6 divided by 2/5
x = ?

We'll be glad to check your answer.

Answer 3

Yes. The total bill is $15.

You could set it up this way:
3/4 x = 12

Answer 4

I am only in 5th grade and not using x yet. This is part of parts and whole fractions.

Answer 5

You found the right answer. :-)

What do you think the answer is to your other problem?

Answer 6

I think the answer to my first problem is 15 for the total bill but I am just guessing. I need to explain the answer.

Answer 7

You paid 2/5 of the bill (1 - 3/5 = 2/5)

To do that you need to divide 6 by 2/5.
6 divided by 2/5 = 6 x 5/2 = 30/2 = 15

Answer 8

5th grade fractions least to greatest

example: 7/12 _____3/9
