Answer:
9/5
Explanation:
original fraction : x/y
new fraction = .9x/(.5y)
= 9x/5y
(9x/5y) / (x/y)
= 9x/5y * y/x
= 9/5
= 1.8
so it increased by 80%
e.g suppose we had 100/200 or 1/2
new fraction = 90/100 or 9/10
new ratio = (9/10) / (1/2)
= 9/5

<h3>What is the standard deviation?</h3>
The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.
The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.
Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.
