Answer:
Jason is 14 year old.
Step-by-step explanation:
Given: Joe, John and Jason are each a year apart in age.
Sum of their age is 39.
Lets assume the age of Joe be x
∴ Age of Jahn will be 
And age of Jason will be 
Now, putting up an equation for the sum of their age.
∴ 
Opening the parenthesis.
⇒
⇒
Subtracting both side by 3
⇒ 
Dividing both side by 3
⇒
∴ 
Hence, Joe is 12 year old.
Next subtituting the value of x to find age of Jason and John.
Jason= 
∴Jason= 14 years.
John age= 
∴ John Age= 13 years.
Hence, Jason is 14 year of age.
Answer:
6.75 hour is approximated to 7 hours
Step-by-step explanation:
Given
Time = 6.75 hours
Required
Round to the nearest hour
The time given is given in base 10 and the conversion can be done in two ways.
1. Convert directly by approximation.
Approximating 6.75 to the nearest whole number gives 7.
Hence, 6.75 hours = 7 hours
2. Convert to time equivalent then approximate time
This is done as follows

Convert decimal to fraction

Simplify to lowest term

Convert hour to minute
There are 60 minutes in an hour



The rule of time approximation is that; if the minutes is between 0 and 29, it'll be rounded to 0; else, it'll be rounded up to 1
Going by the rule, 45 minutes will be approximated to 1 hour.
This gives


Hence, 6.75 hour is approximated to 7 hours
