Simplest form -> 3/434

Explanation:

When simplifying a fraction you always would like to find a common number that goes into both the denominator and numerator, so both values can be simplified by that common number. This number has to be the highest value that can fit into both numbers.

As 1818 is the lowest number, that common number must be ≤1818. By trial and improvement, we can conclude that 66 is the highest common multiple that can fit into both numbers. Therefore we divide both 1818 and 2424 by 66 to simplify the fraction.

18/24 -> 3/4182434

As...

18/6=3186=3

24/6=4246=4

therefore 18/24 ->3/4

3/4

Explanation:

I will show two methods:

Method 1:

We can rewrite 18 as 2*3*3 and 24 as 2*3*4. This may seem strange, but it will prove to be very useful. Our new fraction is:

(2*3*3)/(2*3*4)

(cancel(2*3)*3)/(cancel(2*3)*4)

Here, the 2s and 3s on the top and bottom will cancel, and we're just left with 3/4.

Method 2:

Alternatively, this is the more traditional method. We need to divide the numerator and denominator by a common factor. We can divide by 6 to get:

3/4

18/24=3/4

Explanation:

The first thing to recognize is that 18=2*9=2*3*3 and 24=2*12=2*2*6=2*2*2*3

So, 18/24={2*3*3}/{2*2*2*3}

From here, you can cancel terms appearing in both the numerator and denominator:
{cancel(2)*cancel(3)*3}/{2*2*cancel(2)*cancel(3)}=3/{2*2}=3/4
