4/7 + 1/3 = get common denominator 12/21 + 7/21 = 19/21 is your answer add
You re-scale the fractions so that their denominators are the same. The the numerator of the answer is the sum of the numerators of these new fractions and the denominator is the new denominator.Thus 1/3 + 2/7 = 7/21 + 6/21 = (7 + 6)/21 = 13/21.
Multiply the numerator and denominator of the fraction you have by the same number. 4/7 = 8/14 = 12/21 and so on.
To find the equivalent fraction to 2/7, you need to multiply both the numerator and denominator by the same number. In this case, multiplying 2 and 7 by 3 gives you 6/21. Therefore, the equivalent fraction to 2/7 is 6/21.
1/3 + 4/21First find the least common denominator which is 21.1/3 = 7/21So, 7/21 + 4/21 = 11/21
To solve 3/4 - 6/7... First make the denominator the same in both fractions. 3/4 = 21/28 and 6/7 = 24/28. This gives the answer of -3/28
6/7 + 1/3 You need to find the common denominator 18/21 + 7/21= 25/21= 1 and 4/21
No, because 3/4 is equal to 21/28 and 7/9 is equal to 21/27. 3/4 is less then 7/9 because of the denominator.
To start of you can simplify the equation by making a common denominator, "1/3 - 3/7" 3 and 7 are your given denominators, so let's expand them to make the equation a little simpler, the lowest common number divisible by both our given denominators is 21, so lets multiply our numerators to match that to make the first part of the equation fit into our common denominator we multiply the numerator by the same amount as the the denominator so 1 * 7 makes our numerator 7 3 * 7 makes our denominator 21 7/21 now we do the same to the second portion 3 * 3 makes the numerator 9 3 * 7 makes the denominator 21 9/21 now the equation can be much more simply seen as 7/21 - 9/21 so the answer is -2/21 or to answer the question numerically 21 goes into 2 0.095238095 ext. times
a fraction that is equivalent to 4 and has a denominator of 7 = 28/7
The denominator of 3/4 is 4 The denominator of 7/10 is 10 4 and 10 are not the same number so the two fractions are said to have unlike denominators.
Just multiply the numerator and denominator by the same number: 7/9*2/2= 14/18 7/9*3/3=21/27 7/9*4/4=28/36
