(i) Before adding or subtracting any two or three fractions first we need to consider the denominator of the fractions.
(ii) If the denominators are same,we can put only one denominator and we can add or subtract the numerator.
(iii) If we have different denominators, we should take L.C.M of the fraction and we need change them as same.Then we can add or subtract.
multiplying two fractions we do not have to consider the denominators.We
should multiply numerator with numerator and denominator with
denominator. fraction word problems 3 fraction word problems 3
A ream of paper weighs 12 ½ kg What is the weight per quire, if 20 quire make one ream?
In this problem we have weight of a ream. The weight of one ream is 12 ½ and if 20 quire makes one ream now we need to find
the weight of one quire. To solve this problem we have to use division. We need
12 ½ by 20 to get weight of one ream.
Weight of 20 quires = 12 ½ kg
To find the weight of 1 quire we need to divide weight of 20 quire by 20.
Weight of 1 quire = Weight of 20 quires / 20
Weight of 1 quire = 12 ½ ÷ 20
Here we have to change this mixed fraction into improper fraction
= (24+1)2 ÷ 20
= 25/2 ÷ 20
= 25/2 x 1/20
