Answer:
Option B - Tenths
Step-by-step explanation:
Given : Number rounded 0.799 to 0.8.
To find : To which place value is the number rounded?
Solution :
According to place value system,
Ones Tenths Hundredths Thousandths
0.799- 0 7 9 9
0.8- 0 8
As
0.8 have one decimal places so the number 0.799 hounded from one decimal places.
Around one decimal place is tenth.
Therefore, Tenth place value is the number rounded.
So, Option B is correct.
Firstly it is important to make both the units same for creating a
ratio. Here one of the number mentioned is in centimeter while the other number that is mentioned is in millimeter.
We already know
1 cm = 10 mm
Then
120 cm = 10 * 120 mm
= 1200 mm
Now we can go for creating the required ratio.
So the ratio that compares 1200 mm to 80 mm is = 1200:80
= 120:8
= 15:1
So the correct ratio is 15 to 1. The correct option among all the options given in the question is option "C".
