First you find the least common denominator (LCD)of the two denominators.Then multiply the denominators.(example: 1/2 + 1/4 is the problem 1/2 and 1/4 LCD=4 1/2 x 2 =2/4 2/4 + 1/4 =3/4). personally I think fractions are hard so I don't blame you for asking this question
As a rational fraction it is 1/2.As a decimal fraction it is 0.5
It is: 1 and 1/2 = 3/2 as an improper fraction
10
1 All of these numbers are primes. * * * * * That is the HCF or GCF. The LCD is 42
