G(f(2)) means work out whatever f(2) is then plug this into g(x).
So f(2) is 3 because we just find the x-value 2 in the left hand column and read across. This is 3.
So then we find g(3) by finding the x-value 3 in the left hand column and read across. This is 10.
So g(f(2)) = 10
- 84.7 + 59.2, this is your expression
Multiply the 6 (the denominator), and the 13 (the whole number). To this product, add the 5 (the numerator).
<span>It then gives you 83, which is now the numerator for the improper fraction, and use the 6 as the denominator for the improper fraction.
Therefore the mixed number (13 6/5) is now 83/6 written as an improper fraction.</span>
