GCF of 25, 35 and 45 is 5
Step-by-step explanation:
The greatest factor that divides all given numbers is called the greatest common factor.
In case of 25, 35 and 45, the greatest number that will divide all three will be the GCF
For that, we have to find the factors of all numbers
By observing the factors we can say that the greatest common factor is 5
Hence,

<u>Skills needed: Time Units Conversion</u>
Step-by-step explanation:
1) First, we need to understand how to convert between hours, minutes, and seconds.
There are 60 minutes in 1 hour ==> 1 hour = 60 minutes
There are 60 seconds in 1 minute ==> 1 minute = 60 seconds
- This means that there are 3600 seconds in 1 hour ()
- This also means that there are 60 minutes in 1 hour
2) We are trying to find how many minutes (or seconds) 40% of an hour is.
---> When converted to decimal,
40% of an hour = 0.4 hours
Since there are 60 minutes in an hour, there are minutes in 0.4 hours.
so, 24 minutes in 0.4 hours.
Since there are 3600 seconds in an hour, there are seconds in 0.4 hours.
so, 1440 seconds in 0.4 hours.
