(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.
(iv) For multiplying two fractions we do not have to consider the denominators.We should multiply numerator with numerator and denominator with denominator.
Peter bought 1
⅛ m of iron wire and 2 ⅔ m of copper wire. How much wire did he buy altogether?
Peter had bought two types of wires with different measurements.One is iron wire which is 1 ⅛ m long and another is copper wire which is 2 ⅔ m long.Now we have to find how much of wire did he buy altogether.To solve this problem we have to apply the concept of addition.We have to add length of both the wires to find the total length.
Length of iron wire = 1 ⅛ m
Length of copper wire = 2 ⅔ m
Total length of wires = 1 ⅛ + 2 ⅔
[Now we have to convert these mixed fraction as improper fraction]
= (8+1)/8 + (6+2)/3
= (9/8) + (8/3)
The denominators of two fractions are not same so we have to take L.C.M
L.C.M = 8 x 3
= (9/8) x (3/3) + (8/3) x (8/8)
= (27/24) + (64/24)
= (27+64) /24
Now we have to convert this improper fraction as mixed.For that we have to divide 91 by 24. If we do so we will get 3 as quotient 19 as remainder and 24 as divisor.So the final answer is 3 (19/24)
