: 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
Контрольные работы. 5 класс. С образцами решения. : Usually involving the total distance or amount
: The numerator must be greater than or equal to the denominator ( Possible values: 38three-eighths of them are girls
: Find the numbers that satisfy both conditions. The numbers work for both. 3. Solving Fraction Equations Example : Solve and 10x10 over x end-fraction
: Since there are 3 such parts, multiply the result by 3. 6×3=186 cross 3 equals 18 Final Result : There are 18 girls. 2. Understanding Improper Fractions Problem : For which natural values of is the fraction x6x over 6 end-fraction proper, and 10x10 over x end-fraction
