Why a fraction calculator?

An ordinary calculator turns every fraction into a decimal, which is exactly what you do not want when a recipe, a woodworking plan or a maths worksheet speaks in fractions. Converting back by hand is slow and error-prone. Fraction Calculator Plus keeps everything in fractions: two and three quarters plus one and five eighths gives a mixed number you can use right away. That is useful in the kitchen when scaling a recipe up or down, in the workshop and on building sites where measurements are given in inches and fractions, and for pupils and parents checking homework. Seeing the decimal equivalent next to the fraction also helps learners understand how the two relate. The app is deliberately simple: a keypad designed for fractions and a clear display.

Who uses it

Home cooks halving a family recipe, carpenters adding up board lengths, quilters working out fabric pieces, and pupils learning to add fractions with different denominators all benefit. Teachers can use it in class to check worked examples quickly, while parents can confirm an answer without redoing the whole exercise.

Guide: a first calculation

1. Install the app from Google Play and open it.
2. Enter the whole number, then the numerator and denominator of the starting value.
3. Choose the operation: add, subtract, multiply or divide.
4. Enter the second value and tap equals.
5. Read the simplified fraction and the decimal result.

Tips

• For recipes, multiply every ingredient by the same fraction to scale the whole dish.
• For measurements, round only at the end to avoid adding up small errors.
• For homework, solve by hand first and use the app to check the answer.
• If a result looks odd, check that you entered a mixed number rather than a plain fraction; the whole-number field is easy to overlook.

Ads and privacy
