To answer thie question, you must first develop a proportional statement that compares the liters of fuel used to the distance driven. Considering the subject matter of your question, said statement should be formatted like this:

(255L/340km)=(x/100)

Since this is a proportional statement, you can scale up or down the relative unit to complete the statement. In this case, you will be solving for liters, represented by x, so solve the statement using a ratio for the other side of the equation, in this case the denominators:

340/100

You should get 3.4. That is what you will be scaling the other unit with. Now it is a simple matter to substitute for the numerators:

255/3.4=x

After solving this equation, your final answer should be x=75.

Hope that helps.

11 1/2 and 13 3/4 is?

Tpy6a [65]

This would depend on what you are asking for.

If you are adding the two numbers(which the word and is implying) you’re answer is 25 1/4.

You get this by finding a common denominator. In this case, that can be 4.

Turn 1/2 in to 2/4.

Next, you add 11 and 13 to get 24.

Then, you’ll add 2/4 and 3/4. You will get 1 1/4

Add 24 and 1 1/4. You have your answer of 25 1/4

Bonnie with you $1000 from her saving account. She spent 1/5 of the money on traveling arrangements. She spent 2/3 of the remain

Softa [21]

If Bonnie spent 1/5 of $1,000 on traveling arrangements, she spent $200 on traveling arrangements.

1/5×1,000 = 200

Then she spent 2/3 of the remaining amount at the hardware store. The remaining money is $1,000-$200.

1,000-200 = 800

2/3×800 = 533 1/3

Since we are dealing with money here, 533 1/3 would become $533.33.

Then she treated her family with lunch with the remaining money. Well, the money she had left would be $1,000-$533.33.

1,000-533.33 = 466.67

So she had $466.67 remaining.

Well, after she spent that portion of $466.67 for a lunch, she had $300.50... meaning she spent $166.17 on the lunch.

466.67-300.50 = 166.17

So... Bonnie spent $166.17 on the lunch.
