Question

how to multiply a whole number with a fraction for example 3 X 1/5 i need steps

Answer 1

Multiply 3 times 5, then add one.
Afterwards put the number you get over 5.

Answer 2

3/1x1/5 would equal 3/5

Multiply numerators together, then multiply denominators together. To turn 3 into a fraction, put it over 1. 3/1=3. So then multiply 3 by 1 and 1 by 5 to get 3/5

Answer 3

\[3 \frac{1}{5}\]

That's what it is. Then after doing what I suggested you end up with:

\[\frac{16}{5}\]

Answer 4

thanks i get it for this problem but multiplying fractions has its rule for every different problem

Answer 5

I think she is multiplying whole # x fraction, not converting a mixed number to an improper fraction...?

Answer 6

Oh I see how that can be confusing.

Answer 7

Shameful. They should have kept mixed fractions in this form:

\[3 + \frac{1}{5}\]

Which would be distinguishable from
\[3 \dot\ \frac{1}{5}\]

Answer 8

Like @Deanozaur said, it's sometimes easier to do this problem type if you write the whole number so that you can "treat it" like a fraction:

\(5\cdot \dfrac{1}{3}=\dfrac{5}{1}\cdot \dfrac{1}{3}\) and then just multiply across num'r, and across den'r, as with any fraction multiplication.

Answer 9

\(5\cdot \dfrac{1}{3}=\dfrac{5}{1}\cdot \dfrac{1}{3}= \dfrac{5\cdot1}{1\cdot3}= \dfrac{5}{3}\)

Answer 10

Yes, but @DebbieG I can see how one could get confused if they saw a mixed fraction of this form:

\[3 \frac{1}{5}\]


That's all I was pointing out

Answer 11

That also looks like 3 times 1/5 even though it isn't

Answer 12

The main point to remember is that you write any whole number as a fraction, just by putting it over a den'r of 1.

Answer 13

Huh? @Hero I was addressing the op's question. I wasn't responding to you, other than the one post where I pointed out that you had misinterpreted the question.

Answer 14

I do see your point, although I thought her question "how to multiply a whole number with a fraction for example 3 X 1/5" was pretty clear what she meant....

Answer 15

I thought she was referring to the process of multiplying with mixed numbers.

Answer 16

Thanks for the medal :)

Answer 17

Oh, I did 5 x 1/3, not 3 x 1/5, but the concept is the same so you can see the example I did, @suzy4321

Answer 18

See @DebbieG, we all make mistakes.

Answer 19

I thought she was referring to the process of multiplying with mixed numbers.

Answer 20

That also looks like 3 times 1/5 even though it isn't

Answer 21

Yes, but @DebbieG I can see how one could get confused if they saw a mixed fraction of this form:

\[3 \frac{1}{5}\]


That's all I was pointing out

Answer 22

Yes, we all make mistakes. I wasn't putting you down for your mistake; I was pointing it out so that her ACTUAL question could be answered properly.
Yes, I know what you thought she was referring to.
Yes, I suppose that a person could mix up mixed numerals and the product of a whole number and a fraction, although the notation is not identical, so it's really just a matter of not using sloppy notation.

I was just trying to help her with her question, did not mean to start a debate with you.

Answer 23

Why do you have to assume that we're having a debate rather than a discussion?
