Ok - these always need a little of a review to make sure we"re comment the ideal thing.

You are watching: What is 5 percent of 25

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

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

"...is 5" tells us what the answer we"re trying to find is. So us have:

#25xxP=5# - 25 times part percentage equates to 5.

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

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

Percent have the right to be written as: #("some number")/100#

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

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

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

#color(white)()#

Multiply by 1 and you perform not change the intrinsic value. However, 1 comes in plenty of forms.

#color(white)()#

Multiply #5/25# through 1 however in the type of #1=4/4# giving:

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

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

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

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

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

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

#5/25 xx100%#

#=20%#

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