ACoachCalc Fraction Calculator

iOS iPhone

ACoachCalc is a powerful learning aid that combines Coaching Calculators and mini-Guides to take students step-by-step through fraction basics and solving of simple linear equations.

Fraction modules focus on proper and improper fractions such as 7/24 and 8/3 having numerators and denominators up to 99. Modules also cover addition and subtraction of mixed and whole numbers.

Students develop their skills quickly as they work with the calculator and see each step of a process in detail :

- Addition by multiplying denominator method
- Addition using the Least Common Denominator

- Subtraction by multiplying denominator method
- Subtraction using the Least Common Denominator

- Multiplication
- Multiplication with cross canceling

- Division
- Division with cross canceling

- Comparison by multiplying denominator method
- Comparison by Least Common Denominator method
- Comparison by cross multiplication method

- Conversion of mixed numbers to improper fractions
- Conversion of improper fractions to mixed numbers

- Equivalent fractions using the LCD
- Reduction using the GCD (GCF)

- Prime factorization by a factor tree

- Finding the LCM by prime factorization
- Finding the LCM by listing multiples

- Finding the GCD by prime factorization
- Finding the GCD (GCF) by listing divisors

Linear equation modules focus on solving of one, two and multi-step equations:

- One-step such as x − 5 = 3
- Two-step such as 2x + 5 = 9
- Multi-step such as 3x − 5 = x + 7

ACoachCalc is a member of the Fraction Series comprising ACoachCalc Fraction Calculator, BasicFrac Fractions, MulDivFrac Fractions, CompareFrac Fractions and ConvertFrac Fractions.
