I need this by tomorrow morning

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?

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?

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.

Yes. The total bill is $15.

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

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

You found the right answer. :-)

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

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.

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

5th grade fractions least to greatest

example: 7/12 _____3/9

To find the total bill, we need to determine the part of the bill that your friend had to pay, and then use that information to calculate the whole bill.

Let's break down the problem step-by-step:

Step 1: Assign variables to the unknowns.
Let's call the total bill "B."
We know that you paid $6 of the bill, so we can assign the remaining amount your friend paid as "F."

Step 2: Set up an equation based on the given information.
It is mentioned that your friend paid 3/5 of the bill, so we can write the equation as:
F = (3/5)B

Step 3: Substitute the given value and solve for the unknown.
Since you paid $6, we can substitute that into the equation:
$6 = (3/5)B

Step 4: Solve for B.
To isolate B, we can multiply both sides of the equation by the reciprocal of (3/5). The reciprocal of (3/5) is 5/3:
$6 * (5/3) = B

Simplifying this expression:
$30/3 = B
$10 = B

So, the total bill is $10.

If you need to split the bill evenly, you and your friend will each pay $5.
