I need help please please I appreciate it! ):

Answer 1

Answer:

!. Scale factor = 5

2. Scale factor = $\frac{1}{5}$

Step-by-step explanation:

scale = $\frac{length in drawing}{actual length}$

1. To increase the numbers, let the scale factor be $\frac{5}{1}$ = 5. So that;

0.05 x 5 = 0.25

$\frac{1}{2}$ 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 $\frac{1}{5}$. So that;

0.05 x $\frac{1}{5}$ = 0.01

$\frac{1}{2}$ x $\frac{1}{5}$ = 0.5 x $\frac{1}{5}$ = 0.10

7 x $\frac{1}{5}$ = 1.40

13 x $\frac{1}{5}$ = 2.60

25 x $\frac{1}{5}$ = 5.00

102 x $\frac{1}{5}$ = 20.40
