Answer:

No, you don't.

Step-by-step explanation:

The denominator only changes if you're multiplying/dividing. You may need to create an <em>equivalent fraction</em> to add the fractions together, but you <em>don't</em> add or subtract the denominator.

Hope this helps! Have a great day!

Answer:

No, you adjust the numerator and denominator to a common denominator, then do the addition/subtraction operations with with the numerator, and finally reduce it to the lowest fraction.

Example:

1/3 + 3/4 = ?

change to a common denominator  (12 works for 3 and 4)

4/12 + 9/12 = ?

add the 9 and 12

4/12 + 9/12 = 13/12

reduce to lowest form

12/12 = 1 1/12

What is the Lcm of 2 and 7
wel

Answer:

14

Step-by-step explanation:

The least common multiple is a number that both numbers can multiply something to get to, and the smallest possible common one.

Let's try listing out the multiples of 2:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

And the multiples of 7:

7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Notice that both have the number 14 in common, and it is the first number that they do so.  There are lots of other multiples that they have in common too, but 14 is the least.
