Set up problem then find the sum simplify 3/7 +1/4
3/7 +1/4
Multiples of 7: 7, 14, 21, 28
Multiples of 4: 4, 8, 12, 16, 20, 24, 28
So the common denominator is 28
28 / 7 = 4
4 * 3 = 12
So -- 3/7 = 12/28
(12/28) + (7/28) = 19/28
use a common denominator. Then you have
12/28 + 7/28
not so hard now, eh?
To find the sum of 3/7 + 1/4, we first need to find a common denominator for these fractions.
To do this, we find the Least Common Multiple (LCM) of the denominators, which in this case is 28.
Next, we convert the fractions to have the common denominator of 28.
For the first fraction, multiplying both the numerator and denominator by 4 gives us (3/7) * (4/4) = 12/28.
For the second fraction, multiplying both the numerator and denominator by 7 gives us (1/4) * (7/7) = 7/28.
Now that the fractions have the same denominator, we can add them together.
12/28 + 7/28 = 19/28.
Therefore, the sum of 3/7 + 1/4 is 19/28.
To find the sum of fractions, we need to have a common denominator.
To do this, we first need to find the least common multiple (LCM) of the denominators, which in this case are 7 and 4.
For the number 7, the multiples are: 7, 14, 21, 28, 35, 42, 49, ...
For the number 4, the multiples are: 4, 8, 12, 16, 20, 24, 28, ...
As you can see, the least common multiple (LCM) of 7 and 4 is 28. Therefore, we need to convert the fractions 3/7 and 1/4 so that they both have a denominator of 28.
To convert 3/7, we multiply the numerator and denominator by 4:
(3/7) * (4/4) = 12/28
To convert 1/4, we multiply the numerator and denominator by 7:
(1/4) * (7/7) = 7/28
Now that both fractions have a denominator of 28, we can add them together:
12/28 + 7/28 = 19/28
So, the sum of 3/7 and 1/4, simplified, is 19/28.
