4 0

A) fifth = 5/5 (this is a fraction) 1/5 is 1 fifth of 1. Get what i'm saying? So then the will be 5 fifths in a whole

B) ok turn 2 1/3 into a improper fraction and that will be 7/3

C) ok so 4 (a whole number) is 20/5 so you divide 20/5 with 2/5 (ignore this if you don't know what i'm talking about this is in middle school) so that will = 10

A store has a 25\%25% off sale on coats. With this discount, the price of one coat is \$34.50$34.50. What is the original price

Answer:

$46

Step-by-step explanation:

A percent is a portion of 100. If we receive 25% off then we pay 75% of the price. 100%-25%=75%. $34.50 is 75% of the original price. We find the new price through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio of $ to $.

$\frac{75}{100} =\frac{34.50}{y}$
