★ TODAY'S NUMBER

3/4
means three out of four parts, like 3 slices of a 4-slice pizza!

if you eat 3 slices and your friend eats 1, you ate 3/4 of the pizza. they ate 1/4. together = 1 whole!

CHAPTER 01 · 1.4BEFORE · AFTERPAGE 07

what I thought vs what's actually true

✗ BEFORE

bigger number = more

I thought 1/8 was bigger than 1/2 because 8 is bigger than 2 (oops!)

✓ AFTER

smaller pieces = less!

if you cut a pizza into 8 pieces, each piece is tinier than if you cut it into 2.
