First you need to find a common denominator. So in this case its 4 And whatever you do to one number to do the the other So 4 x 1 is 4 so you have to multiply its numerator by 1 which would be 3 And 2x2 is 4 so multiply it’s numerator by 2 which is 10 Now your equation would look like this : 3/4 + 10/4 Now the easy part, adding
3 + 10 = 13 And you keep the denominator the same So it would be 13/4 Now you need to simplify 13/4 to 3 1/4
the method is pretty easy.we find the LCM of the denominator and then see in how many times it comes in the denominator we then multiply the numerator of the given denominator by its multiple of the LCM .Lemme show u how:
The word problem is based on division ratio so u have to divide by five so 100 divided by five is 20 meaning the collector has to sell 20 band posters.
