Keep the whole the same size
Half of a small sandwich and half of a large sandwich are equal fractions but not equal quantities of food. These two strips always represent the same-sized whole.
Equivalent Fractions Visual Lab: Same Amount, More Equal Parts
More pieces.
The same amount.
Split each piece into smaller equal parts. The numbers get larger, but the shaded length stays put. Build an equivalent fraction and see why it works.

EXPLORE THE RESULT
1/2 = 3/6
Start with 1 of 2 equal parts shaded. Split each part into 3: there are now 6 parts, and 3 are shaded. Both strips show half of the same-sized whole.
Multiply both numbers
Multiplying only the numerator changes the amount. To keep the fraction equivalent, multiply numerator and denominator by the same nonzero number.
Read the bottom number carefully
A larger denominator means smaller individual pieces when the whole stays the same. It does not by itself mean a larger fraction.

Questions before you continue
Can zero have equivalent fractions?
Yes. Zero shaded parts remains zero when both numbers are multiplied by a positive whole number.
Why is the numerator limited?
This lab focuses on fractions from zero to one whole. Enter a numerator no larger than the denominator.
Is this a timed quiz?
No. Change the controls and explain what stays the same. There is no score or timer.
Which side of one half?
Keep the whole the same size. Look at the fraction and decide whether it covers less than half, exactly half, or more than half. Then uncover the strip to check.
