Multiplying Fractions Practice!

Here is the link to the online practice for multiplying fractions!

Remember you must only have numerator and denominator format, so if you have mixed numbers, you must convert to improper fractions using the "texas" method first!

Perimeter, Circumference, and Area Review

Perimeter is the total distance around an object. There is a specific formula for perimeter of a rectangle, P = 2L + 2W, but for other shapes, you just add all the sides up.  Because circles don't have sides that  we can put a ruler to and measure, we have to find a different way to find the total distance around the circle. We call this, circumference. You can find circumference using 2 formulas: C = pi x  diameter or C = 2 x pi x radius. The reason there are two formulas is because 2 radii = 1 diameter. You have to look at what the problem gives you. Remember, perimeter and circumference both measure the distance around the outside of an object!

Area is the total spaced covered inside an object. It's the flat space that something occupies. you must look at the shape and determine what it is so you can pick the right formula! The formulas can be seen below. Make sure you choose the right one to solve!

Volume Assisstance!

I wanted to post some helpful tips on finding the volume of an object. Volume is just an extension of area. It is an object that has multiple layers. To find the volume, you find the area of the first layer, then multiply it by how many times it is stacked. There is an example below and more practice on the web-link.

V = Bh 
Volume = Area of base* x height

*** Because there are so many formulas areas, you have to choose the right one!
