1 is what percent of 5?

2 Answers

Answer:

#20%#.

Explanation:

To calculate the percentage, we use the formula:

#5xxx/100=1#

#1cancel5xxx/(20cancel100)=1#

#x/20=1#

Multiply both sides by #20#.

#(cancel20xxx)/cancel20 = 20xx1#

#x=20#

Answer:

#1/5 = 20%#

Explanation:

Percent, fractions and decimals are all different ways of showing the same value. They are interchangeable.

"What percent is 1 out of 5?"

One way to find a percent:

find an equivalent fraction with a denominator of 100.

#1/5 color(blue)(xx 20/20) = 20/100" "rarr color(blue)(xx 20/20=xx1)#

#20/100 = 20%#

A second way to find a percent:

#"fraction" xx 100%#

#1/5 xx color(blue)(100/100) = 20%" "rarr color(blue)(xx100/100 = xx1)#

A third way to find a percent:

#1/5= 1 div 5#

#1 div 5 = 0.2#

# 0.2 = 2/10 = 20/100 = 20%#

(the third method is the easiest if the denominator is a prime number or has a factor of 3, 7, 11 and so on)
