2/3 + 3/4
First, we need to find a common denominator.
2*4/3*4 = 8/12
3*3/4*3 = 9/12
Now add the numerators.
9+8 = 17
17/12 = 1 5/12
Answer: 1 5/12
5 * 3/4 = 5/1 * 3/4 = 15/4
15/4 = 3 3/4
Answer: 3 3/4
2/3 + 3/4 For this, you want to cross multiply To do this, you do the first numerator (2) multiplied by the second denominator (4), and the first denominator (3) multiplied by the second numerator (3).If you draw lines between the two numbers you are multiplying, a 'cross' is made. Add these two numbers together to make the new numerator. For the denominator, multiply the bottom two numbers. Next simplify the new fraction (Follow attached image)
