Question

2/3 * 1/5? I have tofind the sum and simplify if possible help?

Answer 1

@Pine We have to find the least common denominator, or the smallest number 3 and 5 can go into.

Answer 2

1/3

Answer 3

Nope

Answer 4

And please no direct answers.

Answer 5

I wasn't asking for the answer I was asking for how to do it..

Answer 6

@Pine What is the smallest number that 5 and 3 can both go into?

Answer 7

Ok so the lcm would be 15?

Answer 8

Yes.

Answer 9

take 3 * 5 to get the common denominator

Answer 10

So you would multiply the denominators to a number that would equal 15. So what would you multiply 3 to to get 15?

Answer 11

@Pine

Answer 12

I would multiply 5 to get to 15

Answer 13

Yes, but you would have to multiply 5 to the numerator also, to keep it balanced.

Answer 14

So 13/15?

Answer 15

No...

Answer 16

Wait wait. I'm so confused

Answer 17

@Pine Listen to me please. Since you multiply 5 to 3, you also have to multiply 5 to 2 to keep the fraction balanced.

Answer 18

5 x 2 = ?

Answer 19

10

Answer 20

So 2/3 * 1/5= 10/15* 3/15??

Answer 21

No..

Answer 22

Hold on. So we got our first fraction, which is 10/15. Now we need the second fraction.

Answer 23

Wait, yes you are correct.

Answer 24

Can you correct my mistake there then?

Answer 25

Oh crap.

Answer 26

1/5x2/3 can be changed to 10/15x3/15 so 13/30

Answer 27

I can't believe I forgot.

Answer 28

You have to multiply straight across.

Answer 30

So 10/15 * 3/15 so I got it right the very first time.?

Answer 31

\(\Huge\frac{2}{3}\Huge{x}\frac{1}{5}\)

Answer 32

Actually, you just multiply straight across.

Answer 33

So It's 2 x 1 for the numerator, and 3 x 5 for the denominator.

Answer 34

30/15????????? Or am I incredibly un-coherent?

Answer 35

I said multiply straight across...

Answer 36

My gosh my brain is dead

Answer 37

2 x 1. that's the numerator. 3 x 5. That's the denominator.

Answer 38

2/15
