Which of the numbers 3 / 5 and 3 / 6 is greater?

One way to compare the two fractions would be to both have the same denominator, so that numerators will be easily compared.
The common denominator of 5 and 6 is 5*6=30.
In order to obtain the common denominator, the first ratio will be amplified with 6 and the second ratio will be multiplied with 5.
3 / 5 and 3 / 6
3*6/5*6 and 3*5/6*5
18/30 and 15/30
0.6 and 0.5
0.6 > 0.5
So 0.6=3/5 is bigger.
Another way to compare would be to consider the rule that if the same number is divided by more consecutive numbers, differen as size, the smaller result would be found from dividing the number to the the biggest of these numbers and the smallest result, from dividing to the smallest of these numbers.
In our case, the biggest is 3 / 5, because 3 is divided by the lowest.
When the numerator of two fractions are same, then the fraction with smaller denominator is greater.
I this question the two fractions are, 3/5 and 3/6. They have a common numerator, that is 3. Therefore we can directly conclude that fraction with smaller denominator is greater of the two.
Thus 3/5 is greater than 3/6.
we solve it mathematically;
also we have
3/6 can be reduced to 1/2 which is 0.5
3/5 can be changed to 6/10 which is 0.6
3/5 is greater than 3/6 because 0.6 is greater than 0.5
Clearly, 3/5 is greater than 3/6. You may figure this out mathematically or you may figure it out simply by logic.
By logic, look at what a these fractions mean. In three fifths, you are taking three and dividing it five times. In 3/6, you are taking the same three and dividing it six times. If you cut a pie in five pieces, the slices will be bigger than if you cut it in six pieces. Therefore 3/5 is greater.
You can figure this mathematically as well. The least common multiple of 6 and 5 is 30 so we will make both into fractions with 30 on the bottom.
We multiply the first fraction by 6 and get 18/30 and we multiply the second by 5 and get 15/30. 18 is more than 15, so the first number is greater.
3/5 is greater than 3/6.
Just imagine the slices of a pizza. It should help you more on fractions.

since the L.C.M of 5 and 6 is 30
we will make both the denominators 30
3 /5 = 3*6/5*6 = 18/30
3/6 = 3*5/6*5 = 15/30
On comparing the numerators we find,
so, 18/30 > 15/30
therefore 3/5 > 3/6

3 / 5 and 3 / 6
the both have a common multiple of 30 try to get the denomanaters the same
`3 / 5 xx 6 = 18/30 `
`3/6 xx 5= 15/30 `
3/5 is greater than 3/6
3 / 5 and 3 / 6
Well first you can find out the decimal value for both of these
3/5 =.6 while 3/6 =.5
There 3/5 is bigger since it is more than a half
We need to compare these to fractions: (3)/(5) and (3)/(6).
There are several ways. In one way, you must realize that (3)/(6) is (1)/(2) and that (3)/(5) is greater than (1/2).
Another way is to convert these fractions to decimals since they are easy:
(3)/(5) becomes 0.6
(3)/(6) becomes 0.5
Lastly, the best way is to realize that when fractions have the same numerator but different denominators, the one with the smaller denominator is the larger fraction.
In order to find whether 3/6 or 3/5 is bigger you can change these fractions into decimals. For example ,
3/6 = .5 ; 3/5 = .6
Since .6 ( 3 / 5 ) is greater than .5 ( 3 / 6 )
the answer is 3/5 is greater than 3/6
I had trouble with fractions too but I understood it better when I had examples.
For 3/5 and 3/6
so imagine that you have 2 pizzas of the same size
you cut one pizza into 5 equal pieces and the other into 6 equal pieces
if you take three slices from the first pizza then it would be more pizza than three slices from the second pizza.
also in any case where the top numbers of fractions are the same then the one with the lower denominator is larger.
3 / 5 __ 3 / 6
There are two ways you can do this convert both numbers into decimals which will get you
3 / 5 = 0.60
3 / 6 = 0.50
This 3 / 5 being the greatest
Or you can give each fraction common denominators which is one by
3 / 5 X 6 / 6 = 18/30
3 / 6 X 5 / 5 = 15/30
Again the first one is the greatest.
One way to see which of the fractions are bigger is by looking at the numerators. In this case, they are the same number, 3. Next, you could look at the denominators. They are different: 5 & 6. To put it simply, a pizza was cut into 5 slices and another was sliced into 6 pieces. They were the same size. Three slices of the 5 slices pizza would obviously be bigger.
