Well you can change 1/3 to 2/6, since you can multiply the numerator and denominator by the same number and the fraction will still be the same.
With 2/6, you can divide by 2 to get 1/6 and 1/6.
So addends are 1/6 and 1/6.
6 1 / 5 = 31 / 5;
8 3 / 10 = 83 / 10;
But, 31 / 5 = 62 / 10 ;
62 / 10 - ( - 83 / 10 ) = 62 / 10 + 83 / 10 = 145 / 10 = 29 / 2 .
Well, let’s say the survey is to see how many kids have a pet fish.
So what we can do is basically instead of picking specific people, you could do the first 50 people who were enrolled into your school or something that doesn’t relate to the fish at all.
