The answer is -40 because if you get rid of the negative sign and add instead of subtract... you get 40 so its like adding in the opposite direction.
You have 1 out of 5 chances to get a A in the spinner
<span>You have a 1 out of 6 chances to get a 4 </span>
<span>1/5 times (x) 1/6 = 1/30</span>
Well you know you keep the 7. 1/3 well you see it as .3333 so just go 7.33 because 7.333 and since it's a 3 you keep it.
You need to find what percentage the difference is of 72.
First, subtract 60 from 72:
72-60=8
Next, divide 8 by 72:
8/72=0.1111
To convert this decimal to a percentage, multiply it by 100:
100*0.1111=11.11
The percent decrease is 11.11%.
Hope this helps!!
