Rewrite the fraction pair with common denominators:
1/3 and 1/2
3/4 and 7/8
To rewrite the fraction pair with common denominators, you need to find the least common multiple (LCM) of the denominators, which in this case are 3 and 2.
To find the LCM, you can list out the multiples of each denominator until you find the lowest common multiple:
The multiples of 3 are: 3, 6, 9, 12, 15, ...
The multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, 16, ...
From the lists of multiples, you can see that the first common multiple of 3 and 2 is 6. Therefore, the LCM of 3 and 2 is 6.
Once you have the LCM, you can rewrite the fractions with the same denominator:
1/3 can be rewritten as (1/3) * (2/2) = 2/6
1/2 can be rewritten as (1/2) * (3/3) = 3/6
Therefore, the fraction pair with common denominators is 2/6 and 3/6.
