Answer 1

[1] H 2.4

Let us turn the pictures into equations, using the key given. Then, we will solve.

x + x +
`(1)/(4)`x + 1 + 1 + 1 = x + x + x +
`(1)/(2)`x

2x +
`(1)/(4)`x + 3 = 3x +
`(1)/(2)`x

`(9)/(4)`x + 3 =
`(7)/(2)`x

3 =
`(5)/(4)`x

x = 2.4

[2] J

We can tell the first two options are incorrect because there was a change in size, not position.

Option H would make the shape bigger, but it becomes larger. This means the answer is option J.
