When adding or subtracting fractions, there is one big rule: make sure the denominators are the same first!

As long as the denominators (the numbers on the bottom of the fraction) are the same, you can get an answer by adding the numerators (the numbers on top) and keeping the denominator the same.

********Here's an example********

2/3 + 3/3

First, make sure the denominators are the same. Since the number on the bottom of each fraction is the same, namely 3, we can proceed without worry.

Now add the numerators. The numbers on top are 2 and 3. 2 + 3 = 5.

The final answer is 5/3. We added together the numerators to get the top number, and kept the denominator the same for the bottom number.

***************************************

Try adding 3/4 and 4/4 together on your own now before you look ahead.

To get the answer, let's follow the process.

Make sure the denominators match. They do, so we can proceed.

Add the numerators. 3 + 4 = 7.

Keep the denominator the same. The denominator is 4.

Your answer is 7/4!

Do you have any other questions about the process? Was this helpful?

Keep on working! you got this!

A sphere with radius 16 m is cut by a plane that is 9 m below its center. what is the best approximation of the area of the circ
alexdok [17]
The complete question in the attached figure

we know that
the equation of a sphere is
(x-h)²+(y-k)²+(z-l)²=r²

<span>let's assume that the center of the sphere is at the origin
</span>so
(h,k,l)-------> (0,0,0)
for r=16 m
(x-h)²+(y-k)²+(z-l)²=r²-------->  (x)²+(y)²+(z)²=16²

for z=9 m
(x)²+(y)²+(9)²=16²--------> (x)²+(y)²=256-81--------> (x)²+(y)²=175
the radius of the circle is r=√175 m
so the area of the circle A=pi*r²-----> A=pi*175-----> A=549.5 m²

the answer is 
the area of the circle is 549.5 m²
