I have a hard time with fractions so I usually just go into my calculator and change it to a decimal. For example with -5 1/3 I would insert 1/3 into my calculator to change it to a decimal and then simply tack on the -5 to it. So in decimal form 1/3 is 0.333... so with the -5 added on its -5.333... Do the same for the other number and then divide. You will get -1.9393... all you have to do is go into your calculator and try out 11/12 or 31/33 to see which equals 0.9393... because those are the only options with a -1. In this case 31/33 equals 0.9393 s -1 31/33 is the answer

Will give crown thingy if right Can you find the area and circumference of a circle given the radius or diameter?

Answer:

Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.

Step-by-step explanation:

i) to find the area of a circle or circumference the radius , r, is required.

ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is $d = \frac{r}{2}$ .
