write equivalent fractions with a common numerator. 1/3 and 2/4. 2/5 and 4/12.
2/6 and 2/4
4/10 and 4/12
Math:
somehow it wrong
maybe you are confusing numerator with denominator
To write equivalent fractions with a common numerator, you need to find the least common multiple (LCM) of the denominators.
For the first set of fractions, 1/3 and 2/4, we need to find the LCM of 3 and 4. The multiples of 3 are: 3, 6, 9, 12, 15, 18, ... and the multiples of 4 are: 4, 8, 12, 16, 20, 24, ...
The LCM of 3 and 4 is 12, as it is the smallest number that appears in both lists.
To convert 1/3 to a fraction with a denominator of 12, you multiply both the numerator and the denominator by 4 (which is 12 divided by 3). Thus, 1/3 is equivalent to 4/12.
To convert 2/4 to a fraction with a denominator of 12, you multiply both the numerator and the denominator by 3 (which is 12 divided by 4). Thus, 2/4 is equivalent to 6/12.
So, the equivalent fractions with a common numerator for 1/3 and 2/4 are 4/12 and 6/12.
For the second set of fractions, 2/5 and 4/12, we need to find the LCM of 5 and 12. The multiples of 5 are: 5, 10, 15, 20, 25, 30, ... and the multiples of 12 are: 12, 24, 36, 48, ...
The LCM of 5 and 12 is 60, as it is the smallest number that appears in both lists.
To convert 2/5 to a fraction with a denominator of 60, you multiply both the numerator and the denominator by 12 (which is 60 divided by 5). Thus, 2/5 is equivalent to 24/60.
To convert 4/12 to a fraction with a denominator of 60, you multiply both the numerator and denominator by 5 (which is 60 divided by 12). Thus, 4/12 is equivalent to 20/60.
So, the equivalent fractions with a common numerator for 2/5 and 4/12 are 24/60 and 20/60.
