First, Ann posted 1/3 of the 45 fliers. 1/3 * 45=15, meaning that she posted 15, leaving 30 fliers. Next, she posted 2/5 of the remaining fliers. 2/5 * 30 = 12, so she posted 12 more fliers. 30-12 is 18, so she has 18 left over.
Answer:
The radius and the diameter of the circle are 11 cm and 22 cm respectively.
Step-by-step explanation:
The radius of a circle is a line segment extending from the center of a circle or sphere to the circumference or bounding surface, while the diameter of a circle is a straight line passing from side to side through the center of a body or figure, commonly a circle or sphere. Since the diameter goes entirely across the circle while passing through the midpoint - or center - of a circle and the radius only goes from the edge to the midpoint, that means the diameter is twice as big as the radius. In this example, the radius is already given to you, which is 11 cm, based on the image. Using this, you can figure out the diameter of that circle would be 
or 22 cm. So the radius of the circle is 11 cm, while the diameter of the circle is 22 cm.
-12 I just did this question In class
I wouldn't say that. It looks to me like you've absolutely got it ... almost.
A). Your fraction is correct. But it's not in simplest form like they want it.
Reduce 18/45 to simplest form. Hint: Divide top and bottom by 9 .
B). They want the percentage that's the same as 18/45 .
Do you remember how to change a fraction to percent ?
A fraction is just a short way to say "division".
" 18/45 " means " 18 divided by 45 ".
Do the division. To change the quotient into percent, multiply it by 100 .
(Same as moving the decimal point 2 places to the right.)
Round it the nearest whole number, if it isn't already a whole number.
C). Again, your fraction is correct, but it isn't in simplest form.
Reduce 27/45 to simplest form. Hint: Divide top and bottom by 9 again.
D). Change this fraction to percent, just like you did for the female fraction.
(Do the division that the fraction says, and multiply the quotient by 100.)
(Round to the nearest whole number percent if it isn't already.)
You already did the technical stuff. I just added some mechanical things.
Yes, since the decimal terminates, it is a rational number.
