Sipho

Sipho and John got the same amount of work; Sipho did 19/34 of his homework, and John did 23/41 of his homework. What percentage of his homework did John do, and what percentage of his homework did Sipho not do?

Final Answer:

a =  56.0976 %
b =  44.1176 %

Step-by-step explanation:

$$\begin{gathered} s=\frac{19}{34}\doteq 0.5588 \\ j=\frac{23}{41}\doteq 0.561 \\ a=j\cdot 100=\frac{23}{41}\cdot 100=\frac{23\cdot 100}{41}=\frac{2300}{41}=\frac{2300}{41}\%=56.0976\% \end{gathered}$$

$b=100\cdot (1-s)=100\cdot (1-\frac{19}{34})=\frac{750}{17}\%=44.1176\%$
