10/50
1/5 because when you see a zero the first rule is to take away the zero's
19/19 + 20/19
3 because it's 39/13 and 13 can go into 39 3 times
12/15
4/5 because when we look at these 2 numbers we can tell that they can be simplified by 3 so it's 4/5
150/500 + 329/500=
479/500 because you add them but you can't simplify them
50/150
1/3 because when you see a zero the first rule is to take away the zero's and it's 5/15 but it's not finished because they can still divide by 5 so the real answer is 1/3
90/100 + 50/10
5 9/10 because 50/10 is 5 as a whole number and 90/100 when you take away the zero's it becomes 9/10 so it's 5 9/10
123/456
41/152 because when you look at these numbers you might be like whaaaaaat but i have a trick and it's called the 3 rule. first add all the numbers up like 123 and it's 6 so can 3 be divided by six yeah! so we do that with the 456 and 15 can be divided by 3 so when we divide by 3 it's 41/152 and can't be divided anymore!
20/5 + 33/100
4 33/100 because as a full number for 20/5 it's 4 and you can't simplify so it's 4 33/100
111112222233333444445555566666777778888899999/111112222233333444445555566666777778888899999
1 they are the same number but super long to make it seen hard! >: )
500/10000 + 10/1000
3/50 because 10/1000 is 100/10000 and 100+500 is 600/10000 and take 2 zero's away so it's 6/100 and simplify it so it's 3/50
