To write equivalent fractions with a common numerator, we need to find the least common multiple (LCM) of the denominators and then divide the LCM by the denominator of each fraction. Here is how you can determine the equivalent fractions:
1) 3/6 and 2/4:
The LCM of 6 and 4 is 12. We divide 12 by 6 to get 2, and then multiply that by 3 to get the equivalent fraction: 3/6 = (2 * 3) / 6 = 6/12.
Similarly, we divide 12 by 4 to get 3, and then multiply that by 2 to get the equivalent fraction: 2/4 = (3 * 2) / 4 = 6/12.
Therefore, the equivalent fractions with a common numerator are 6/12 and 6/12.
2) 2/4 and 3/5:
The LCM of 4 and 5 is 20. We divide 20 by 4 to get 5, and then multiply that by 2 to get the equivalent fraction: 2/4 = (5 * 2) / 4 = 10/20.
Similarly, we divide 20 by 5 to get 4, and then multiply that by 3 to get the equivalent fraction: 3/5 = (4 * 3) / 5 = 12/20.
Therefore, the equivalent fractions with a common numerator are 10/20 and 12/20.
3) 1/3 and 4/5:
The LCM of 3 and 5 is 15. We divide 15 by 3 to get 5, and then multiply that by 1 to get the equivalent fraction: 1/3 = (5 * 1) / 3 = 5/15.
Similarly, we divide 15 by 5 to get 3, and then multiply that by 4 to get the equivalent fraction: 4/5 = (3 * 4) / 5 = 12/15.
Therefore, the equivalent fractions with a common numerator are 5/15 and 12/15.
