Answer 1

Answer:

cycle=33 students, driven=132 students, walk=55 students

Step-by-step explanation:

solution

60+15+x=100 to get the remaining percentage

x=25

15÷100×220=33

60÷100×220=132

25÷100×220=55

Answer 2

Answer:

a) 33 students cycle to school

b) 132 students are driven to school

c) 55 students walk to school

Step-by-step explanation:

Finding the number of students that arrive to school by different means of transport.

Question (a) How many students cycle to school?

since 15 % of the students cycle to school :

15% * 220 students

=33

hence 33 students cycle to school

Question (b) How many students are driven to school?

since 60 % of the students are driven to school

60% * 220 students

= 132

hence 132 students are driven to school.

Question (c) How many students walk to school?

since the remaining students walk to school . we can find this by removing the number of students that cycle and are driven to school from the total amount of students in the school.

33 students walk to school

132 students are driven to school

the remaining students walk to school

= 220 - 33 - 132

= 55

hence 55 students walk to school.
