10/18 because 18-8=10 and the total amount is 18 so the fraction is 10/18
Answer:
Hi
Step-by-step explanation:
You have to subtract it because you add a negative and positive fraction together you can add a positive with a positive or vice versa but you can add n and p together so you have to subtract.
Hope it helps
The highlighted sector is exactly 3/4 of the circle area, because
is 3/4 of
which is a complete rotation.
Since you are given the radius, you can compute the area as
![A = \pi r^2 = 16\pi](https://tex.z-dn.net/?f=%20A%20%3D%20%5Cpi%20r%5E2%20%3D%2016%5Cpi%20)
So, 3/4 of this area would be
squared cm.
The remaining sector, of course, is
squared cm.
Answer:
3 3/8 cups of flour
Step-by-step explanation:
So, we know that 2 1/4 is the normal amount of flour you would use in the recipe. but you don't want to do normal. You want to make 1 1/2 times more than you usually do.
To do this, first figure out what half of 2 1/4 is.
(2 1/4) /2 = 1 1/8
Then, because you are looking to use 1 1/2 times more flour, simply add the 1 1/8 to the 2 1/4
You end up using 3 3/8 cups of flour.
