Question

I need help please please I appreciate it! ):

Answer 1

!. Scale factor = 5

2. Scale factor =
`(1)/(5)`

Explanation:

scale =
`(length in drawing)/(actual length)`

1. To increase the numbers, let the scale factor be
`(5)/(1)` = 5. So that;

0.05 x 5 = 0.25

`(1)/(2)` x 5 = 0.5 x 5 = 2.50

7 x 5 = 35.00

13 x 5 = 65.00

25 x 5 = 125.00

102 x 5 = 510.00

2. To decrease the numbers, let the scale factor be
`(1)/(5)`. So that;

0.05 x
`(1)/(5)` = 0.01

`(1)/(2)` x
`(1)/(5)` = 0.5 x
`(1)/(5)` = 0.10

7 x
`(1)/(5)` = 1.40

13 x
`(1)/(5)` = 2.60

25 x
`(1)/(5)` = 5.00

102 x
`(1)/(5)` = 20.40
