Answer:
Answer of your asked question is attached
Step-by-step explanation:
What is fraction and what is improper,mixed,like and unlike fraction?(fraction is a part of a whole.eg.if you eat a piece of , then it will become 3/4th pizza.improper fraction-it is the fraction in which the upper part will be greater than the lower part.lower part will be less than the upper part(lower part of the fraction is called as Denominator and the upper part is known as Numerator.
Mixed fraction- it is a fraction in which there is whole and the fraction part.eg- you ordered a medium size 1 cheese (medium size pizza has 4 slices)pizza and a panner.you ate I slice of cheese pizza and 3 slices of panner pizza,so 3 1/4.
Like fraction- it is a fraction in which all denominators of fraction will be same.eg.2/6,5/6,3/6 etc
Unlike fraction-it is a fraction in which all the denominators of the fraction will be different.eg.3/4,8,10,9/14 etc
How to make unlike to like fraction.eg- the lcm of some number is 15
Now the given fraction is 2/3 and 3/5
So take denominators and check whether the lcm comes in the tables of 3,5
3×5=15
5×3=15
So,
2/3×5/5=10/15
3/5×3/3=9/15.
How to convert mixed into proper fraction?(proper fraction mean the Numerator will be less than the denominator and the denominator will be greater than the Numerator.eg.12/25,8/10)(to convert mixed into proper fraction-eg.3 5/4-now multiply 4×3=12 and add 5 to 12=17=17/4( write the same denominator given in the fraction)
NOW LET US DO THE PROBLEM
Given= 2 1/4+5/12 , 3 2/3+2 1/3
First,convert the mixed fraction into improper fraction
(2 1/4+5/12) , (3 2/3+2 1/3)
( 9/4 + 11/2) , (11/3 + 7/3)
Second,find the LCM of the denominators-4,2,3,3.
the LCM=12
Make it unlike fraction to like fraction
9/4×3/3=27/12 , 11/2×6/6=66/12 , 11/3×4/4=44/12 , 7/3×4/4=28/12
So add 27/12+66/12=93/12
44/12+28/12=72/12
So 93/12 is greater
By how much = 21
