Let the total time is x min
Since he practices for 98 min
Since this amount of time = 70% of his total time
Since his total time is x
70% x (x) = 98
Divide 70 by 100 to change it from percent to decimal
[tex]\frac{70}{100}=0.70[/tex]0.70 x (x) = 98
Divide both sides by 0.70 to find x
[tex]\begin{gathered} \frac{0.70x}{0.70}=\frac{98}{0.70} \\ x=140 \end{gathered}[/tex]The total time of he practices in is 140 min
