Write 5.1/4 as an improper fraction

0:00:05.224,0:00:07.779
Let me remind you an improper fraction

0:00:07.779,0:00:11.726
is one where the numerator is gretaer than or equal

0:00:11.726,0:00:17.624
to denominator, absolute value of numerator

0:00:17.624,0:00:20.317
is greater than or equal to

0:00:20.317,0:00:34.807
absolute value of denominator

0:00:36.711,0:00:38.058
In this situation right here we have

0:00:38.058,0:00:40.194
a mixed number where 5 is the whole number

0:00:40.194,0:00:43.723
and 1/4 is a proper fraction as numerator

0:00:43.723,0:00:49.621
is less than denominator

0:00:49.621,0:00:54.219
So write as an improper fraction I will

0:00:54.219,0:00:55.380
show you the methodology

0:00:55.380,0:01:02.067
So 5.1/4, the methodology is simple

0:01:02.067,0:01:09.126
5 is the same thing as 20/4

0:01:09.126,0:01:13.305
So 20/4 + 1/4 = 21/4

0:01:13.305,0:01:17.624
Another way to think is 5 x 4 = 20 + 1 = 21

0:01:17.624,0:01:21.533
So its 21/4

0:01:21.533,0:01:29.792
You take the mixed number or you take the whole part

0:01:29.792,0:01:32.067
of the mixed number multiply it with

0:01:32.067,0:01:35.782
the denominator & add the numerator to it.

0:01:35.782,0:01:45.024
So let us see why it works.

0:01:45.024,0:01:50.132
lets us see what 5.1/4 is

0:01:50.132,0:01:56.309
We have 5 wholes, this is one whole

0:01:56.309,0:02:05.667
let me copy it five times

0:02:05.667,0:02:14.533
So that is 2, 3, 4 & that is 5

0:02:14.533,0:02:30.867
So we have 5 wholes and then we have 1/4

0:02:30.867,0:02:38.933
1/4th of a whole is like this

0:02:43.000,0:02:46.400
To write it as a improper fraction

0:02:46.400,0:02:54.200
Divide each of the wholes into 1/4ths

0:02:54.200,0:03:02.533
This is 4, 1/4ths, another 4,1/4ths another 4,1/4ths

0:03:02.533,0:03:11.400
this is another 4, 1/4ths. So how many

0:03:11.400,0:03:25.000
1/4ths we have it is 20 , 1/4ths in green

0:03:25.000,0:03:32.600
That is the same thing as 5

0:03:37.600,0:03:48.733
and then we can add to that 1/4ths.

0:03:48.733,0:03:59.200
Then we will get 21/4.

0:03:59.200,0:04:02.867
That is the conceptual way of how it works.

0:04:02.867,0:04:06.733
Multiply the whole number by the denominator

0:04:06.733,0:04:10.267
and add the numertaor to it

0:04:10.267,0:04:13.533
5.1/4 = 21/4

0:04:13.533,0:04:19.400
5.1/4 =( ( 5x4) + 1)/4
