Find a common denominator.
we'll pick 12 so...
1/4 = 3/12
1/3 = 4/12
So you gave your sisters
3/12 + 4/12 = 7/12
You keep 12/12 - 7/12 = 5/12
First you simplify both sides of the equation, then isolate the variable and that’ll give you c=3b/4

C) SST means "Total Sum of Squares''. It's source is total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
