Multiply alternately by 0.5 and 10.
20
10,000
500 2500.
1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500.
Multiply by 5 4*5 = 20 20*5 = 100 100*5 = 500 500*5 = 2500
500
500
20
assuming 100 is dollars 500 . $1 = 5 $10 = 50 $100 = 500
500 * 0.2 which is 100 actually if you are multiplying 500x0.2 it would = 10 not 100.
10,000
Because you are doubling the amont and halving the percentage. 10% of 250 = 250*10/100 = 250/10 = 25 5% of 500 = 500*5/100 = 500/20 =25
The percentage of 100 to 500 is 20%.
2, 4, 10, 20, 50, 100, 250, 500
1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500.
100/(500/100) = 20%
