1. 10.1 Pan Balance Problems
SRB 212 & 213

2. Pan Balances Scales should always be balanced. (Hands-on Equations)
You may remove the same amount of the same object from both sides of the balance. (Hint: remove the smaller amount from each side)
Use your operations to figure out the equivalent balances.

3. Example 1 One diamond weighs as much as _____ squares.
One diamond weighs as much as three squares.
One diamond weighs as much as _____ squares.
I can remove 2 squares from each side.
If 2 ◊ = 6 □, then
1 ◊ = 3 □
□□□□□□□□
□□◊◊
□□□□□□ ◊◊

4. Example 2 Example 2 One x weighs as much as _____ y’s.
One x weighs as much as four y’s.
One x weighs as much as _____ y’s.
I can remove 8x’s from each side.
I can remove 14y’s from each side.
If 16y’s = 4x’s, then 4y’s = 1x 8x
30y
12x
14y
16y 4x
