Simplify: <br><br> 0.007 km : 0.021 km : 14 m
Igoryamba

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)

Step-by-step explanation:

Data:

Let the probability of the correct answers be denoted by the letter C.

The probability of no more than 35 defective CD's  can be 35 or less. Therefore, it is presented as follows:

P ≤  35

Let, the probability of more than 44 correct answers can be presented like this:

P > 44

Therefore, combining the two inequalities gives an area at the right of 35.5
