So 4 hours
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600seconds
4 hours=3600 seconds times 4=14400seconds
so 8 out of 14400
8/14400=2/3600=1/1800
percent means parts out of100 so
x%=x/100
the reatios are equal to
1/1800=x/100
mulitply both sides by 100
100/1800=x
1/18=x
divide out
0.055555555=x
round
0.06%
Answer:
The sum of two rational numbers will be rational.
Step-by-step explanation:
Rational numbers are numbers that can be written, are integers, and are not zero. So, any rational number plus another rational number will be rational because their sum will also be an integer, writable, and not a zero.
