yes you do
No because in order to subtract or add fractions the denominator of the fractions must be the same and if they are not then the lowest common denominator of the fractions must be found. Having subtracted or added the fractions then it may be possible to simplify the result.

I've assumed it's the Pacific Ocean ever since he "rode the Hasselhoff" in the first big movie.
this is how you find equivalent fractions... OK if you have 3 8th as a fraction, you can times 8 by 2 and get sixteen. what ever you do to the bottom you do to the top. so you also times 3 by 2 and get 6. your new fraction is 6 16th. get it? you can times the number by any other number. but i say times it by 2 because it's easier:)
Yes, but only if the two fractions are the same or equivalent fractions (other than 0).
Certainly, if you multiply fractions for instance.
Fractions can be real, imaginary, or complex. In your case, we're willing to bet that any fraction that you've ever encountered so far has been a real number.
Infinitely many ways, since if you have found one way then take one of the fractions and replace it by an equivalent fraction. Repeat for ever.

Yes, there are times when you multiply fractions.
You find the common denominator for both fractions and which ever has the highest numerator is greater.

If working in fractions, then you must make the fractions have the same denominator (the number on the bottom). To decide what the denominator should be you find what number does 8 and 7 go evenly into (8 x 7=56). Therefore 56 is the new denominator, now you must make the fractions in the question equal the same amount with a denominator of 56. WHAT EVER YOU DO TO THE DENOMINATOR YOU MUST DO TO THE NUMERATOR (TOP NUMBER) TO KEEP THE FRACTION THE SAME VALUE. Then 3/8 = 3x7/8x7 = 21/56, and 1/7 = 1x8/7x8 = 8/56. Now thee question becomes 21/56 - 8/56 = 13/56
You have to make the fractions improper then you switch the devision sign to the multiplying sign and then you switch the numbers around on the second fraction then you just multiply the fractions. When ever you do this think keep switch flip you keep the first fraction alone you switch the sign then you flip the last fraction. Good luck 😍
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
