Answer:
4
Step-by-step explanation:
13 x 4 = 52 + 7 = 59
It can be helpful to remember that "%" is just a shorthand way to write "/100" (divided by 100, or per 100, or per cent). ("Cent" is often used to refer to 100 or 1/100. A "cent" is 1/100 of a dollar, or 1/100 of an acre, for example. A <em>cent</em>ury is 100 years.)
Make the denominator of your fraction be 100. Multiply numerator and denominator by 20/20.
(2/5)×(20/20) = 40/100 = 40%
You can also get there via decimals.
... 2/5 = 0.4 = 0.40 (40 hundredths) = 40/100 (40 hundredths) = 40%
Or, you can multiply by 100%.
... (2/5)×(100%) = (200/5)% = 40%

Answer:
$2.04
Step-by-step explanation:
Note that: 1 yard = 3 feet.
First, change the amount of yard (6) to feet:
6 x 3 = 18
6 yard = 18 feet.
Note: 18 feet = $36.72
Find the cost per foot (1 feet). Note the equal sign, what you do to one side, you do to the other. Divide 18 from both sides.
(18 ft)/18 = ($36.72)/18
1 ft = 36.72/18
1 ft = 2.04/1
1 ft = $2.04
