How do turn 4/33 into a decimal

I normally just use a calculator to make fractions into decimals. If you need to do them by hand I would suggest watching this video: https://www.khanacademy.org/math/arithmetic-home/arith-review-decimals/decimals-to-fractions/v/converting-fractions-to-decimals

That should be the answer though if you needed to check your work.

Hope this helps!

2008      63.1
2009      63.1 - 1.7
2010      63.1 - 1.7*2
2011      63.1 - 1.7*3

x            63.1 - (x - 2008) *1.7

2018      63.1 - (2018 - 2008) * 1.7

63.1 - (10) * 1.7 = 63.1 - 17 = 46.1

Change from 2008 - 2018 = 63.1 - 46.1 =   17

% of change = change * 100 / initial value = 17*100/67.1 = - 25. 3%.

The negative sign indicates that the change was a decline, instead of an increase.
