Answer:
4 hours
Step-by-step explanation:
We can set up a proportion of kilograms to hours
6 kilograms/3 hours=8 kilograms/x hours
We can cross multiply to get 6x=24 and x=4
The greatest denominator is 105 so he had 98/105 yards of wire and used 75/105 yards of wire from it.
5 is in the tenths place. You would look to the number on the right of it, and if it is bigger than the number 5 you would round up. The number is 6 so you round up a number.
the answer is 243.6
Note: 5 is always the in-between number for rounding.
