i need to know the how to write 75 1/4% as a decimal

75¼% = 75.25% = 0.7525

Your turn. Why was that one trickier than, say 85% ==> ??

i need to know the how to write 75 1/4% as a decimal

75 1/4%

First thing, remove the % symbol.


We now have 75 1/4.


Multiply the denominator 4 by the whole number 75 and then add your answer to the numerator 1. We then divide by 4.


(4 times 75 + 1) divided by 4.


(300 + 1)/4 = 301/4

So, 301 divided by 4 = 75.25

We now move the decimal point two places to the left.

Final answer: 0.7525

NOTE: In my first reply, I forgot to move the decimal point two places to the left.

75 1/4%

First thing, remove the % symbol.\(\displaystyle \text{When you "remove" the percent symbol,}\)
\(\displaystyle \text{you are multiplying the expression by 100, }\)

\(\displaystyle \text{so you must divide 75 1/4 at the same time by 100 to keep}\)
\(\displaystyle \text{the value of the expression the same.}\)

We now have 75 1/4.


Multiply the denominator 4 by the whole number 75 and then add
your answer to the numerator 1. We then divide by 4.


(4 times 75 + 1) divided by 4.


(300 + 1)/4 = 301/4


So, 301 divided by 4 = 75.25


Cool, right?

nyc_function,

\(\displaystyle \text{no, 75.25 is not the decimal which is equivalent to}\) \(\displaystyle 75 \frac{1}{4} \%.\)

tkhunny already showed it is \(\displaystyle 0.7525\)

Thank for correcting my first reply. As you can see, I completed my reply by moving the decimal point two places to the left, which I forgot to do originally. Anyone can make a mistake.

Anyone can make a mistake.

This is a given, so it need not be typed. I saw another person
type that before in some other math site, and I took it as
defensiveness.

Edit:

And there must be dozens of mathematical errors I have made
on this site that should still be corrected.
