MM255-03 Business math and statistical

1.      Lori is baking a cake that requires two and one half cups of flour. Lori poured four cups and one sixth cups  of flour into a bowl.  How much flour should Lori take out of the bowl?  Given parameter: Flour required: 2 ½ cups, asked parameters:  How much should be taken out of the bowl?  Calculation needed:  4 1/6 – 2 ½

Now solved them by using the rules we studied earlier.

1.      Let us find out LCM (Lowest Common Numerator) and make the denominators equal.

2.      LCM of 2 and 6 is 6

So 2 ½ becomes 2  3/6.

3.      4   1/6 – 2  3/6

4.      Now since 1 is less than 3, we need to change the numerators follows:
