The gas tank of your car is 40% full. There are 8 gallons of gas in the tank. What is the capacity of the gas tank?

Answers

Answer 1
Answer: Percentage by which the gas tank of the car is full = 40%
Amount of gas in the gas tank = 8 gallons
Let us assume the capacity of the gas tank = x gallons
Then
40% * x = 8
(40/100) * x = 8
4x/10 = 8
4x = 8 * 10
4x = 80
x = 80/4
   = 20 gallons
So the total capacity of the gas tank of the car is 20 gallons. I hope the procedure is clear to you.

2 divided by 1 and 6/7

Answers

This problem, as written, requires a bit of guessing regarding your intentions.  My interpretation is that you want to do this division:


    2

----------

 1  6/7

If that's correct, here's what to do:  rewrite 1  6/7 as 13/7 (an improper fraction).

Then divide:

   2

--------      This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)

 13/7

Mary bought a paid of jeans and a sweater.The pair of jeans costs $30 and the sweater costs $35 .If sales tax is 6% ,how much did Toby spend in total for the jeans and sweater? Explain please

Answers


$30 + $35 = $65

Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)

$65 + $3.90 = $68.90 ($65 + 6%)

OR

You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)


Write 56:72 in simplest form

Answers

Expressed as a proper fraction in its simplest form, by dividing the numerator and denominator by 8, 56/72 is equal to 7/9 or seven ninths.

Hey there! :D This is a ratio so basically ratios and fractions are the same things! So lets set it up first we do 56/8=7 and 72/8= 9. Also when you are dividing fractions you always have to divide by the same number. So your answer is 7/9.

Hope I helped! ;)
