Answer:
The answer is 1 : 3 : 2
Step-by-step explanation:
First, you have to make them into same unit by converting it into km or m :
1 km = 1000 m
0.007 km = 7 m
0.021 km = 21 m
7 : 21 : 14
OR
14 m = 0.014 km
Then you can simplify it by 7 :
m,
7 : 21 : 14
= 1 : 3 : 2
OR
km,
0.007 : 0.021 : 0.014
= 0.001 : 0.003 : 0.002
= 1 : 3 : 2
(take note: in ratio, it is better to put it in whole number form rather than decimal form)

Answer:
49 third graders
Step-by-step explanation:
From the question:
The music teacher receives 9 boxes of recorders and there are six recorders in each box
The total number of recorders the teacher received =
1 box = 6 recorders
9 boxes = x
Cross Multiply
x = 9 × 6 recorders
x = 54 recorders.
She hands them out to third graders and has 5recorders left .
How many third graders received a recorder?
The amount of recorders shared =
54 recorders - 5 recorders
= 49 recorders
If 1 recorders was given to a third grader,
Therefore, the amount of third graders that received a recorder is 49 third graders
