How it works
Fractions
Pick a fighter, choose Fractions, and trust your numbers. The faster and cleaner you solve, the harder you hit — from gentle early grades all the way to Olympic-level challenges.
A fraction is a slice of something. The bottom number says how many equal pieces you cut; the top says how many you take.
To find 3/4 of 20: cut 20 into 4 equal parts (each is 5), then take 3 of them → 15. Divide by the bottom, multiply by the top.
Type how much that slice is worth.
