The idea
Multiplying by 2/3 means taking 2/3 of something: cut 3/4 into 3 parts, take 2, and you land on 1/2. You took only a part, so it's smaller than 3/4.
A common mix-up
Multiplying always makes a number bigger.
Where it stops working
Only multiplying by something bigger than 1 (like × 3/2) makes it grow: 3/4 × 3/2 = 9/8, to the right of 3/4. Multiplying by something less than 1 shrinks it.
