Question

How do you know when a fraction cannot be simplified no further??

Answer 1

when both numbers cant be divided by the same number

Answer 2

If both the numerator and the denominator cannot be divided by a common factor, then they cannot be simplified any further.

Answer 3

For example:
\(\frac{3}{4}\) cannot be simplified any further because they do not share any common factor(s)

Answer 4

5/6 cant be simplified but 3/6 can

Answer 5

i mean 4/6 not 3/6

Answer 6

Answer 8

You're welcome

Answer 9

no common factors, i.e. you can't divide the same number into the top and bottom

but to recognize this (without using a calculator)
you can learn some tricks.

and at some point, learn the prime numbers (up to say about 100)

Answer 10

Thank you for the links, @phi !!!

Answer 11

Quick question, since you're here. To get the fraction 9/4 to have a denominator of 8, you should multiply that by 2, right? And get 18/8? @phi

Answer 12

yes, you can always multiply top and bottom by the same number
if you want 8 in the bottom, you multiply 4 * 2
but then, to keep the fraction the same, you also multiply the top by 2
