Answer:
1. 8/8 or 1
1. 8/8 or 12.7/18
Solution:
1. 1/8+3/8+4/8=N
because it has the same denominator you just need to add the numerator then copy the denaminator .
1 + 3 + 4 = 8
if the denominator is 8 then this will be the denominator to the sum
N = 8/8 or just a whole 1
2. 8/9-2/4=N
in here the denominator is different not like the number 1 ,so we need to have a new fractions.First multiply the two denominators,then the product will be the new denominators of the two fraction.After that we divide the product to the numerators then we have new fraction.And you can subtract it now.
9 x 4 = 36 ?/36 - ?/36 = N
36 √ 8 = 4
36 √ 2 = 18 4/36 - 18/36 = 14/36
you can also simplify it by dividing the difference to the GCF(greatest common factor)
GCF of 14/36 is 2
14/36 √ 2 = 7/18
N = 14/36 or 7/18
