Explanation:
first, add 3 and 5 together to get the sandwiches robert already made. so you should get 8.
Now, subtract 12 and 8 to get the ham sandwiches (the rest). you should get 4.
So, 4 ( the ham ) should be fractured by 12 ( all kinds of sandwiches robert already made. now your final answer should be :
4/12
How do you write it:
3 + 5
= 8
= 12 - 8
= 4
= 4/12 #
now, 4/12 is already correct. however, you may have to simplify the equation. so now, your final answer should be:
1/3
(my english is not so good so i hope you can understand my explanation well enough.)
