Fractions and geomentry

Math one of an important subject that we need to learn. I’ve learned so much from this term. Fractions and geometry are the lessons that we currently working on.  This what I remember from those lessons.

To multiply fraction with fraction, we multiply its numerator with numerator and denominator with denominator. If we want to multiply fraction with whole number, we just take the whole number and multiply it by the numerator, then we will get the answer. To divide fractions, we need to remember a phrase called “ flip and multiple” those means we have to flip the second fraction and then do the multiplication as normal. If we want to divide it with whole number, just take the whole number and then multiply it with they denominator, we will get the answer. For both multiply and divide, if it is the mixed number, we need to convert it to improper fraction first and then do the math as above. One thing that we really need to remember for the fraction is that, all of the answer that we got from they divide or multiplications are required to be in simplest form.

example

Geometry. To find the area of a triangle, we need to take base multiply with height and then divide it by 2. For the rectangle, to find the area, we need to take height times with base and then we will get the answer. To find the perimeter of the rectangle, we need to take length add with width and then times two.  

Triangle = ( H X B ) divide 2 = Area

Rectangle = H X B = Area

      = ( H + B ) X 2 = perimeter
