Answer: The fraction would be 0.53.
Step-by-step explanation:
Since we have given that

where, A is the constant initial production rate
t is the time.
For 98 years, the production rate in motorcycles per year would be

For 13 years, the production rate in motorcycles per year would be

So, the fraction of their total production was built during the last 13 years would be

Hence, the fraction would be 0.53.
im not for sure but I think the answer is 9! my reasoning is below,,
Step-by-step explanation:

do the crossing method and it would result in this
(49×x) = (63×7)
after simplifying both sides
49x = 441
divide both sides by 49 and the result will be
x = 9 !!
Yes, you can square a negative, however it can only give you a positive answer
however, you cannot root a negative number (if that was what you wanted)
hope this helps
