First, find the total growth over the three months.
The total growth (G) is the sum of the growths in each month:
[tex]\begin{gathered} G=\frac{3}{4}+\frac{1}{2}+\frac{7}{8} \\ \end{gathered}[/tex]Using 8 as a common denominator:
[tex]\begin{gathered} G=\frac{2*3+4*1+1*7}{8} \\ G=\frac{6+4+7}{8} \\ G=\frac{17}{8} \end{gathered}[/tex]The total growth is 17/8.
Second, find the difference between the second and the third month (S).
To find it, subtract the growth of the second month from the growth of the third month.
[tex]S=\frac{7}{8}-\frac{1}{2}[/tex]Using 8 as a common denominator:
[tex]\begin{gathered} S=\frac{1*7-4*1}{8} \\ S=\frac{7-4}{8} \\ S=\frac{3}{8} \end{gathered}[/tex]The difference between the second and third months is 3/8.
Answer:
(a) The total growth is 17/8.
(b) The difference between the second and third months is 3/8.
