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

✅ : The exercises on page 52 are designed to solidify the fundamental understanding of fractions and their basic operations, preparing students for more complex mixed number arithmetic.

: Treating fractions as balanced "math sentences" where both sides must remain equal. x=1720−920x equals 17 over 20 end-fraction minus 9

: Find the numbers that satisfy both conditions. The numbers work for both. 3. Solving Fraction Equations Example : Solve

: The numerator must be greater than or equal to the denominator ( Possible values: : Find the numbers that satisfy both conditions

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

: 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 Solving Fraction Equations Example : Solve : The
