1/3 + 3/5 + 7/10 = 49/30 or 119/30
It simplify to 1
Actually, I don't really think that you can simplify it, because if you convert them into fractions, there all over 1 and you can't simplify it. You can simplify it if it's: 5 plus 7 DIVIDED by 3. That was when you divide the 12 by 3 in fraction form, the 3 and one switch, and u can simplify 3 into 1 and 12 into four, so there by the answer is 4. (Sorry if confusing)
No.
5/7 + 3/7 = 1 1/7 or 8/7. Just add the top numbers then simplify!!
11+(7-3)2=
3
1/3 is in its simplest form.
3+2+3²-1 = 5+8-1=12
1 over 3
The answer would be 1 over 3
