Original
1/4
One of four equal parts is shaded.
A direct fraction answer
Common equivalent fractions for 1/4 are 2/8, 3/12, and 4/16. They use different numbers, but each one names the same one-quarter amount.
Quick answer
1/4 = 2/8 = 3/12 = 4/16
1/4
2/8
3/12
4/16
Every bar has the same width and stops at the same one-quarter point. More pieces do not mean more of the whole.
The short explanation
To make an equivalent fraction, multiply the numerator and denominator by the same nonzero whole number. Start with 1/4, choose a multiplier, and apply it to both numbers. The denominator tells you how many equal parts the whole has; the numerator tells you how many of those parts are shaded.

1/4
One of four equal parts is shaded.
Same change
× 2/2
Both numbers are doubled together.
New name
2/8
Two of eight equal parts cover the same amount.
Use the multiplication rule
Choose any positive whole-number multiplier. Each original fourth is split into that many smaller equal parts, so the number of shaded pieces grows by the same factor.
Multiply by 2
1/4 × 2/2 = 2/8
Split each fourth into two equal eighths. One shaded fourth becomes two shaded eighths.
Multiply by 3
1/4 × 3/3 = 3/12
Split each fourth into three equal twelfths. The shaded length stays one quarter.
Multiply by 4
1/4 × 4/4 = 4/16
Each fourth becomes four sixteenths, so one shaded fourth becomes four shaded sixteenths.
Visual proof
The equal parts get smaller as the denominator grows, but the shaded endpoint remains fixed. That is what “equivalent” means: different names for the same amount.
1/4
Same one-quarter endpoint
2/8
Same one-quarter endpoint
3/12
Same one-quarter endpoint
4/16
Same one-quarter endpoint
Check the answer
You can reduce a proposed fraction back to 1/4, or use cross-multiplication. Both checks compare the value, not just the numbers.
8/32 ÷ 8/8 = 1/4
Reducing both numbers by 8 returns the simplest form.
1 × 8 = 4 × 2
8 = 8
Matching cross-products confirm 1/4 = 2/8.
Common mistake
Do not change only the denominator. Although eighths are smaller pieces than fourths, 1/8 covers only half as much as 1/4.
1/4 ≠ 1/8
1/4
1/8
To make an equivalent eighths fraction, count two shaded eighths: 1/4 = 2/8.
