Let's see what the range of possible values you can have for 1.3540980 if your uncertainty is +/- 2%
2% of 1.3540980 = 0.02 * 1.3540980 = 0.027082
So the lowest possible value for your result is
1.3540980 - 0.027082 = 1.327016
The largest possible result is
1.3540980 + 0.027082 = 1.38117996
Notice that only the 1st 2 digits of the result match which is reasonable since a 2% error means that your result is only accurate to within 1 part in 50.</span>
We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.
Consider the ratio of 1 and 3.5,
1 : 3.5 = 
= 
Reducing the above fraction to its lowest form.
So, we get 
Therefore, the ratio 1 : 3.5 is expressed as 
where 2 and 7 are the whole numbers.

Hello!
OK, so we need to find out 20 km = ? dam
What we know:
1 km = 100 dam
Now, lets multiply to get our answer:
20 × 100 = 2,000
This tells us that 20 km = 2,000 dam
Check:
2,000 ÷ 20 = 10
This tells us that we are CORRECT!
Answer: 20 km = 2,000 dam
Hope this helps! Good luck! (:
