SOLUTION:
7) The times recorded, you count the number of strokes. Total number of strokes = 5 strokes.
8)
fractions (1/4, 3/4, 6/4, 6/4, 6/4)
[tex]\begin{gathered} \frac{1}{4}+\text{ }\frac{3}{4}+\text{ 1}\frac{2}{4}+\text{ 1}\frac{2}{4}+\text{ 1}\frac{2}{4} \\ \text{Total whole number= 1+1+1= 3} \\ \text{Total fractions= }\frac{1}{4}+\frac{3}{4}+\frac{2}{4}+\frac{2}{4}+\frac{2}{4} \\ \text{Total fractions= }\frac{1+3+2+2+2}{4} \\ T\text{otal fractions= }\frac{10}{4} \\ \text{otal fractions= 2}\frac{2}{4}\text{ OR 2}\frac{1}{2}\text{ hours} \end{gathered}[/tex][tex]\begin{gathered} \text{Total hours: 2+2}\frac{1}{2} \\ \text{Total hours: 5}\frac{1}{2}\text{ hours} \end{gathered}[/tex]
9) To calculate the average hours. We add all the hours and divide by 5
[tex]\begin{gathered} 5\frac{1}{2}\div5 \\ \frac{11}{2}\div\frac{5}{1} \\ \frac{11}{2}\times\frac{1}{5} \\ \frac{11}{10} \\ 1\frac{1}{10}\text{ hours} \end{gathered}[/tex]
Final answers:
7) 5 days
8) 5 and half hours
9) 1 and tenth hours
