## Converting Mixed Numbers to Improper Fractions

• 0:01 - 0:05
Write 5.1/4 as an improper fraction
• 0:05 - 0:08
Let me remind you an improper fraction
• 0:08 - 0:12
is one where the numerator is gretaer than or equal
• 0:12 - 0:18
to denominator, absolute value of numerator
• 0:18 - 0:20
is greater than or equal to
• 0:20 - 0:35
absolute value of denominator
• 0:37 - 0:38
In this situation right here we have
• 0:38 - 0:40
a mixed number where 5 is the whole number
• 0:40 - 0:44
and 1/4 is a proper fraction as numerator
• 0:44 - 0:50
is less than denominator
• 0:50 - 0:54
So write as an improper fraction I will
• 0:54 - 0:55
show you the methodology
• 0:55 - 1:02
So 5.1/4, the methodology is simple
• 1:02 - 1:09
5 is the same thing as 20/4
• 1:09 - 1:13
So 20/4 + 1/4 = 21/4
• 1:13 - 1:18
Another way to think is 5 x 4 = 20 + 1 = 21
• 1:18 - 1:22
So its 21/4
• 1:22 - 1:30
You take the mixed number or you take the whole part
• 1:30 - 1:32
of the mixed number multiply it with
• 1:32 - 1:36
the denominator & add the numerator to it.
• 1:36 - 1:45
So let us see why it works.
• 1:45 - 1:50
lets us see what 5.1/4 is
• 1:50 - 1:56
We have 5 wholes, this is one whole
• 1:56 - 2:06
let me copy it five times
• 2:06 - 2:15
So that is 2, 3, 4 & that is 5
• 2:15 - 2:31
So we have 5 wholes and then we have 1/4
• 2:31 - 2:39
1/4th of a whole is like this
• 2:43 - 2:46
To write it as a improper fraction
• 2:46 - 2:54
Divide each of the wholes into 1/4ths
• 2:54 - 3:03
This is 4, 1/4ths, another 4,1/4ths another 4,1/4ths
• 3:03 - 3:11
this is another 4, 1/4ths. So how many
• 3:11 - 3:25
1/4ths we have it is 20 , 1/4ths in green
• 3:25 - 3:33
That is the same thing as 5
• 3:38 - 3:49
and then we can add to that 1/4ths.
• 3:49 - 3:59
Then we will get 21/4.
• 3:59 - 4:03
That is the conceptual way of how it works.
• 4:03 - 4:07
Multiply the whole number by the denominator
• 4:07 - 4:10
and add the numertaor to it
• 4:10 - 4:14
5.1/4 = 21/4
• 4:14 - 4:19
5.1/4 =( ( 5x4) + 1)/4
