Master the translation between parts of a whole!

Step 1 of 4 Slide to divide

Make the bar match the fraction:

{{ (s1.sliderValue / 100).toFixed(2) }}
Step 2 of 4 Build the fraction

Use the place value of the last digit.

Tap numbers to build the unsimplified fraction for:

{{ s2.targetStr }}
{{ s2.selectedNum !== null ? s2.selectedNum : '?' }}
{{ s2.selectedDen !== null ? s2.selectedDen : '?' }}
Perfect Match!
Step 3 of 4 Drag to divide

Divide numerator by denominator.

{{ s3.n }} {{ s3.d }}
{{ step.dividend }} ÷ {{ s3.d }} =
{{ step.done ? step.ans : '?' }}
rem {{ step.rem }}
Decimal Result
0.{{ s3.steps.map(s => s.ans).join('') }}
{{ n-1 }}
Step 4 of 4 Type the pattern

Some fractions repeat forever!

Find the repeating pattern and type it under the bar.

=
{{ s4.sequence }}
{{ s4.prefix }}
{{ s4.input || '_' }}
🏆
