Well dear Kay Kay;

2/3 - 3/8 = ( 16 - 9 ) / 24 = 7/24 = 0.2916
Part b ;

2/3 - 3/8. Make a common denominator which is 3*8 or 24
to get 16/24 - 9/24 = 7/24
Greatest prime factor of 1230.
Let's look at it. It ends in 0, so it is divisible by 10
or 2 and 5.
Now look at 10 *123.
123 is divisible by 3, because the sum of its digits
is 6, which is divisible by 3.
123 = 3* 41.
So your answer is 41.
Just add the numbers in the last problem to get 17.4.
Hope that helps!

i suck at maths, but i think thats right..
(2 / 3) - (3 / 8) = 0.291666667
The prime factors of 1230 are
2 and 3 and 5 and 41
That is, 1230 = 2 x 3 x 5 x 41, and those numbers are primes.
5.5 + 5.8+ 6.1 = 17.4
