Question

I need help please is for tomorrow):

Answer 1

Explanation:

If a number gets increased by scale factor = k

Then k > 1

If the number gets decreased by a scale factor 'k'

Then 0 < k < 1

Let numbers gets increased by the scale factor = 2,

And decreased by the scale factor =
`(1)/(2)`

Numbers Scale up by 2 Scale down by
`(1)/(2)`

0.05 0.05 × 2 = 0.1 0.05 ×
`(1)/(2)` = 0.025

`(1)/(2)`
`(1)/(2)* 2 = 1`
`(1)/(2)* (1)/(2)=(1)/(4)`

7 7 × 2 = 14 7 ×
`(1)/(2)` = 3.5

13 13 × 2 = 26
`13* (1)/(2)=6.5`

25 25 × 2 = 50
`25* (1)/(2)=12.5`

102 102 × 2 = 204
`102* (1)/(2)=51`
