3/5-1/3...to get the simple form of these unlike fractions ..u need to make them into like fractions by taking their LCM and making their denominators same ..and then subtract them if possible then reduce them 3/5 - 1/3
LCM of 3 and 5 =15 ..
=> 3/5 X3 =9/15
=>1/3 X 5= 5/15
9/15-5/15 =4/15
since 4 and 15 dont share any common factor other than 1 , the simplest form of 4/15 remains as it is ..

Hope it helps !!!

ANSWER: 4/15

To find the simple form of both fraction, the denominator (or bottom number) must be the same. So the first step is to look for the same denominator number. To do that, you must find the GCF (greatest common factor) which is 15. This how I get 15
5: 5, 10, 15, 20, 25, 30, 35, 40, 45
3: 3, 6, 9, 12, 15, 1842, 45
So basically, you need to see which number do they have the same. If the question have the same denominator, then you just need to subtract but since our GCF is 15 (it can be 45 too but if you put 45, there would be a lot of works)

So then that we found the GCF which is 15... the equation will be now...

3/5 x 3/3 = 9/15
(3 is suppose to be multipied by both #/# because we need to get 15 on the denominator. The same thing applied to the equation 1/3 but instead, it is multiplied by 5 because 5 x 3 is 15)
1/3 x 5/5 = 5/15

= 9/15 - 5/15 (You shound NEVER EVER SUBTRACT THE DEMONINATOR)
so you subtract 9-5

Final answer is 4/15

Answer from: Quest

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
