I'm embarrassed to ask this since this is basic math, but I honestly don't remember how to do this stuff.

What is 25% of $177.11

I need to know the answer, as well as a detailed breakdown of how you got it.


I have to take a test for an upcoming job and I know there will be a few math problems like this one.

$177.11 x 0.25 = $44.2775

Have a nice day,

Okay, first off, let's break down the meaning of "percent" or "per cent." It means per 100. Thus 25% means 25 per 100, or 25 / 100, or 0.25.

This leaves us with 0.25. Now, how do we get 25% of the $177.11? We multiply by 0.25, leaving us with $44.2775.

I hope this helps!

I get that much. The problem I have is I don't even remember how to multiply .25x177.11:blush

I guess I've relied on calculators for so long that I've forgotten how to do it by hand.

Multiplying by 0.25 is the same as dividing by 4. Why do you need to do it by hand?

Edit: oh, for a job interview/application type thing? I see, I guess. And lots of people don't know how to work out percentages, don't feel too bad.

Will they be wanting you to do any awkward percentages? I think you need to convert it to fractions, like:

25/100 * 177.11/1

er, can anyone take it from here? I hate fractions, can never remember the rules...

Oh, I know, I know! simplify 25/100 by dividing both the top and bottom number by 25, which gives you 1/4. Which makes sense, because 25% is the same as one quarter, right? So that gives:

1/4 *177.11/1

Now, multiply the top numbers together to get the top number of the new fraction, and the bottom numbers together to get the bottom number of the new fraction:

1 * 177.11 = 177.11
4 * 1 = 4

so 1/4 *177.11/1 = 177.11/4

So now you need to divide 177.11 by 4. I hope somebody on the forum can explain long division better than me?

OK, ignore me, Max's ways are better :)

or
25%=10%+10%+5%=10%+10%+10%/2

10% of 177.11=.1*177.11=17.711 approx=17.71
5%->17.711/2=17/2+.70/2 approx=8.50+.35=8.85

17.71
17.71
8.85
+_____
$44.27
Oh that's a neat way of doing it.

Another way is, since 25% is 1/4, it's just a half of a half. So take half of the original (177.11/2 = 88.56) and then half again 88.56/2 = 44.28
