Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.
There are 600 students in this school.
There are two ways (of many) to do this
Method 1:
47/x = 82/73.8
47*73.8 = 82x
3468.6 = 82x
82x = 3468.6
x = 3468.6/82
x = 42.3
---------------------------------
Method 2:
47/x = 92/82.8
47*82.8 = 92x
3891.6 = 92x
92x = 3891.6
x = 3891.6/92
x = 42.3
---------------------------------
Either way, the answer is 42.3 meters
