Ok - these always need a little of a review to make certain we"re answering the best thing.

You are watching: What percent of 25 is 5

"What percent..." asks united state for a percentage. Yes - good.

"...of 25..." asks united state to take it the number (25) and multiply the by the percentage we"re going come find.

"...is 5" tells united state what the answer we"re searching for is. So we have:

#25xxP=5# - 25 times some percentage equals 5.

We have the right to treat P as a variable and also so can divide both political parties by 25:

#P=5/25=1/5=0.2=20%#


*

Percent deserve to be created as: #("some number")/100#

For instance 3% would be #3/100#"~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Write the offered values in the concern as a portion

#" "5/25##color(white)()#

But percent is #("something")/100# for this reason we require to change the 25 in #5/25# into 100.

#color(white)()#

Multiply through 1 and also you do not change the intrinsic value. However, 1 comes in plenty of forms.

#color(white)()#

Multiply #5/25# by 1 but in the type of #1=4/4# giving:

#" "5/25color(magenta)(xx1)" " =" " 5/25color(magenta)(xx4/4)" "=" "20/100#

#color(white)()#

#color(blue)("So "5/25" might be written as "20%#

#2/25 =1/5= 0.2 =20%#


Explanation:

It might aid to compose the concern a small differently.

What percent is #5 " the end of " 25#?

#5/25 = 1/5# already represents the decimal #0.2#.

However to obtain it into percentage format, main point by #100%.#

Note the #xx 100% =xx 100/100 # which is the exact same as a multiplication by #1#, so we do not adjust the value, just what that looks like.

#5/25 xx100%#

#=20%#

Fractions, decimals and percent space all various ways of writing the exact same quantity and they are inter-changeable.
