Question

What is the lowest common denominator of 1/2 and 1/11

Answer 1

Answer:

22

Explanation:

2 and 11 are both prime so their GCF must be 2*11 which is 22.

Answer 2

For this case we have by definition, that the lowest common denominator of two or more fractions, is the number that results from calculating the lowest common multiple of the denominators of those same fractions.

We have the following fractions:

$\frac {1} {2}$ and$\frac {1} {11}$

We look for the least common multiple of 2 and 11:

2: 2

11:11

$l.c.m = 2 * 11 = 22$

Answer:

The lowest common denominator of the fractions is 22
