Answer:
1. (7+3)/2
2. 6, 3
3. 5/6
4. 500, 4000
Step-by-step explanation:
1. We are adding 7 and 3 so use the plus sign, THEN we divide by 2 
Because we are adding first, put parentheses  
(7+3)/2 
2. Nearest whole means whole number (so basically no decimal) 
5.823 --> 6 (because 8 is closer to 10 than 0) 
3.147 --> 3 (because 1 is closer to 0) 
3. 1/3+1/2 
Find a common difference, which is 6
Multiply to get 6
1/3*2= 2/6
1/2*3=3/6
3+2=5/6 (when adding keep denominator the same) 
4. There are 100 centimeters in a meter 
5*100= 500 centimeters
There are 1000 grams in a kilogram
4*1000= 4000 grams 
Hope this helps, lemme know if somethings still unclear!!

If you mean added together 3 times then it would be 6 3/4 and just in case this sounds rude I do not want it to be.
