### EQUATION - VISUAL REPRESENTATION

The following questions show the visual representation of equation.
.1 understand the concept of 'balance'
.2 identify the numerical value or representation of the unknowns in the questions.
.3 how is this related to the concept of 'equation'?
.4 post you answers as comment

1. 1) 2 O's
2) 3 O's
3) 1 O's
4) 2 squares

2. 1. Balance is when the weight of one scale is the same as another, causing the scale's arm to be parallel to the ground.
2. The various shapes.
3. Equation, like balance, is when the value of one side of an equation is the same as the other, with an equal sign in between. Instead of shapes, there are variables.
4.
1. 1 dot is equal to 2 circles.
2. 3 triangles is equal to 3 circles.
3. 1 square is equal to 2 circles.
4. 1 circle is equal to 2 squares.

3. 1(c) 1 dot = 2 circles
2(c) 3 triangles = 3 circles
3(c) 1 square = 2 circles
4(d) 1 circle = 1 triangle

4. 1) 1 dot=2 circles
Ans: 2 circle

2) 1 triangle=1 circle
Ans: 3 circles

3) 1 square= 1 dot
2 circle= 1 dot
Ans: 2 circle

4) 1 Circle=1 triangle
1 circle= 2 square
Ans: 2 square

5. 1) 2 Os
2) 3 Os
3)1 O
4) 2 square

6. .1 A balance is where both sides of the scale are in equilibrium.
.2 They are the different shapes.
.3 It is similar to an equation but they replaced the = sign to a scale and the unknowns and numbers to the various shapes.
.4.1 1 dot = 2 O
.4.2 3 triangles = 3 circles
.4.3 3 circles
.4.4 1 circle = 2 squares
