Step-by-step explanation:
scale =
1. To increase the numbers, let the scale factor be = 5. So that;
0.05 x 5 = 0.25
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 . So that;
0.05 x = 0.01
x
= 0.5 x
= 0.10
7 x = 1.40
13 x = 2.60
25 x = 5.00
102 x = 20.40
