It's C. And to help you understand the process.
1. Divide 3 by 4 which produces 0.75
2. Multiply the result by 100 and append the % symbol
so
3/4 = 0.75
0.75 * 100 = 75
75%
use this it mght help
Let's be careful with our terminology, first: you mean dividing the
numerator BY the denominator! A lot of kids get that wrong.
The basic reason is that division is really what fractions are all
about. In a very real sense, we can say that a fraction is simply a
division we haven't bothered to perform yet, a division problem frozen
in time.
We write "3/4" to mean "I want to divide 3 by 4, but I don't want to
do the work just yet, so I can simplify the work before I finish up."
That's why we use the virgule "/" or the horizontal fraction bar to
signify division in more advanced math (and in computer programming
languages), rather than the old-fashioned obelus.
Let's go back to the basics of fractions to see why I can say this.
What are fractions? The essence of a fraction is a division, a
breaking into pieces. Take a whole object and divide it into 5 (equal)
pieces; each piece is 1/5. We've divided 1 by 5, just as we divide 10
by 5 by dividing a set of 10 things into 5 parts, each of which
consists of 2 objects. So 1 divided by 5 is 1/5; and 10 divided by 5
is the fraction 10/5, which simplifies to 2.
Likewise, we can divide 2 pies into 5 parts by dividing each pie into
5 parts (fifths) and taking 2 of them at a time: 2 divided by 5 is
2/5. The denominator represents the number of parts we divide each
whole into (a divisor); the numerator represents a multiplier, the
number of parts we have.
Let me repeat that, because it's easy to miss: 2/5 MEANS 2 divided by
5. The fraction IS a division.
Now look at the operations on fractions. When we multiply by a
fraction, we're really dividing: 1/2 * 10 is half of ten, or ten
divided by 2, or 10/2 again. Fractions mean division.
So when we want to convert a fraction to an ordinary (decimal) number,
all we're really doing is waking up a division problem that has been
in suspended animation, and letting it continue: "Where was I? Oh,
yeah ... 3 divided by 4 ... that's 0.75."
Here's another approach to the whole thing, focusing more on the
decimals themselves. A (terminating) decimal can be thought of as a
way to represent a fraction whose denominator is a power of ten. So
when we convert 3/4 to a decimal, we are looking for an equivalent
fraction whose denominator is, say, 100:
fraction decimal
3 ?
--- = ---
4 100
How do we do that? We have an object divided into 100 parts, and need
to know how many of them make 3/4 of the object. To do that, we can
multiply 100 by 3/4. But that is 300/4, and we can simplify that by
dividing both the numerator and the denominator by 4:
300 300 divided by 4 75
--- = ---------------- = -- = 75
4 4 divided by 4 1
So 3/4 = 75/100, or 0.75 - and we found the 75 by dividing 300 by 4,
which is exactly what you are doing when you divide 3 by 4 and put in
the decimal point where it belongs, two places from the right.
I hope one of these ideas will help.
3/4=
x/100=
75/100=

75%. This is 75/100 written out.
Think of a dollar = 4 quarters. 3/4 of a dollar would be 3 quarters. Hope that helps
3/4 = .75
Multiply that by 100 to convert to percent, therefore:
.75*100=75%.
Your answer is C.
3/4 * 100 = 75%
Glad to helps! ^_^
= 3/4(100%)
= (3/[4/4])(100%/4)
= 3(25%)
= 75%
Answer: c. 75%
C. 75%
That's kind of an easy one...
