Who has the most pizza?
Hello Everyone! It is the fifth week of math and it July 4th today!! This week we learned how to add, subtract, multiply and divide fractions. Growing up, fractions were always difficult for me to understand and still to this day I have trouble comparing amounts to figure out which one is bigger. Today I am going to show you what helps me to understand when comparing amounts.
When trying to figure out what fraction is bigger compared to another I always find a common denominator and then think of a pizza! Lets use these fractions and put them in descending order.
1/3, 1/6, 2/3, 1/12, 1/4
1.) First, we find a common denominator. We can see that the common denominator is 12
2.) Then we convert each fraction into twelves. 1/3 becomes 4/12
3.) 1/6 becomes 2/12, 2/3 becomes 8/12, 1/12 stays the same, and 1/4 becomes 3/12
4.) We then have 4/12, 2/12, 8/12, 1/12, 3/12
When we have converted all the fractions to the same denominator then we think of a pizza. Imagine a pizza with 12 slices. Would you rather have 1 slice out of the 12 or 8 slices out of the twelve.
When we look at this picture we can now list the fractions in descending order,
8/12, 4/12, 3/12, 2/12. 1/12
Hope everyone has a wonderful 4th of July!!!
