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:
