Actually none of the answers is correct - it's neither 30,900 nor 40,000.
30,944 rounded to the nearest ten thousand will give us 30,000. It's because 30,944 is closer to 30,000 than to 40,000.
The answer is 1/4
because you can add the 3/8 and 1/4, which it will be 5/8.
Then add 5/8 and 1/8 then it eqaul to 6/8
then subtract 1 by 6/8
then you got 2/8 or 1/4
