Answer:
I think the answer is b 2x bigger
3. yes because 15 divided by 5 and 27 divided by 9 both result in the same answer; 3.
4. No because 3/4 is not a whole number, while 4/3 is. For this to be an equivalent ratio, the second number would have to be something like 6/8.
Gauss's approach is to add the same sequence in reverse order, namely
S=1+3+5+7+......+95+97+99
S=99+97+95+......+7+5+3+1
---------------------------------------
2S=(1+99)+(3+97)+(5+95)+......(95+5)+(97+3)+(99+1)=50*100=5000
=> sum = (2S)/2 = 5000/2=2500.
