How do you solved addition fraction which not the same denominator?
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.
What is 4 over 7 plus 1 over 3?
4/7 + 1/3 = get common denominator 12/21 + 7/21 = 19/21 is your answer add
How do you do equivelent fractions?
Multiply the numerator and denominator of the fraction you have by the same number. 4/7 = 8/14 = 12/21 and so on.
What is the equivalent fraction to 2 over 7?
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.
What is 3out of 4 minus 6 out of 7?
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
What is 1 over three add 4 over 21?
1/3 + 4/21First find the least common denominator which is 21.1/3 = 7/21So, 7/21 + 4/21 = 11/21
What is the sum of 6 over 7 and 1 over 3?
6/7 + 1/3 You need to find the common denominator 18/21 + 7/21= 25/21= 1 and 4/21
Is 3 over 4 greater than 7 over 9?
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.
What is the sum of one third minus three sevenths?
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
What is three and three fourths plus two and seven twenty eighths equal?
The answer is 6. Here's how to determine that: 1. Start with the original fractions of 3 3/4 + 2 7/28 2. Obtain a common denominator so they can be added together. To do that, multiply the numerator of the fraction with the smallest denominator by the same value it takes to increase the denominator to the same value as the other denominator. In english: in the fraction 3/4, "3" is the numerator and "4" is the denominator. We have to get the "4" to match the larger denominator ("28") of the 7/28 fraction. To do that, look at both denominators ("4" and "28") and determine if the smaller denominator ("4") can be multipled to equal the larger denominator ("28"). Since we know that multiplying 4 by 7 equals 28, we know that we can make the denominators equal by multiplying the 3/4 fraction by 7. So, doing so, we then have a fraction that is 21/28. Both numbers in the fraction are multipled by the same amount. 3. So, now you have 3 and 21/28 + 2 and 7/28. 4. Add the fractions (21/28 and 7/28) together, which gives you 28/28. Since the result is a whole number (a fraction with matching numerator and denominator), we no longer need to write it as a separate fraction. Therefore, the new formula looks like this: 3+2+1 (the 1 was originally 28/28). Added together, the result is 6.
What fraction is equvilent to7 over 9?
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
What is the unlike denominators for 3-4 plus 7-10?
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.
