The first thing to do is the make the denominators of the fractions the same.
5/10 of the pupils walked to school and 2/10 of the pupils came to school by bus.
5/10 + 2/10 = 7/10.
10/10 - 7/10 = 3/10.
<span>3/10 of the pupils came to school by car. </span>
70 = 50 * x/100
x = 70/50*100 = 140
Seventh is 140% of 50.
