: Understanding that the top number indicates how many of those parts are being considered.

: Usually involving the total distance or amount after several parts are consumed or traveled. Step-by-Step Analysis of Key Problems 1. Calculate a Part from a Whole Problem : In a school, there are 48 fifth-graders. 38three-eighths of them are girls. How many girls are in the fifth grade? Divide the total by the denominator : To find one part ( 18one-eighth ), divide the total number of students by 8. 48÷8=648 divided by 8 equals 6
