: Treating fractions as balanced "math sentences" where both sides must remain equal.

: 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 : Treating fractions as balanced "math sentences" where

: The numerator must be smaller than the denominator ( Possible values: Calculate a Part from a Whole Problem :

This page tests a student's ability to transition from whole numbers to "parts of a whole". It emphasizes: Divide the total by the denominator : To

x=1720−920x equals 17 over 20 end-fraction minus 9 over 20 end-fraction : Keep the denominator the same.

: Understanding that the bottom number indicates how many equal parts the whole is divided into.
