1) Macints survey, 12 children walk to school, 4 come on bike and 11 come by car
what fraction travel by car?
Answers
Step-by-step explanation:
let the total no. of students be x
number of students who come by car = 2x/5
number of students who come by bus = x/4
number of students who come by walk = x - (2x/5 + x/4) = x - 13x/20 = 7x/20
number of students who come by walk on their own = (7x/20)/3 = 224
7x/60 = 224
x = 224×60÷7 = 1920
Answer:
11/27
Step-by-step explanation:
Given :- Number of children that walk to school = 12
Number of children that come to school by bike = 4, and
Number of children who come to school travelling by car = 11.
To Find :- Fraction of children that travel by car
Solution :-
Number of children that walk to school = 12
Number of children that come to school by bike = 4, and
Number of children who come to school travelling by car = 11.
Total number of children = 12 + 4 + 11
= 12 + 15
= 27
∴ Fraction of children that travel by car
= number of children travelling by car ÷ total number of children
= 11 ÷ 27
= 11/27
Therefore, fraction of children that travel by car = 11/27.
