Successive numbers are obtained by dividing the previous number by 5, hence 200, 40, 8, 1.6. 0.32, 0.064,.....etc.
1.6
8.525 = 341/40 or 821/40
There are 200 centimetres in 2 metres. Therefore, 80 centimetres is equal to 80/200 x 100 = 40 percent of 2 metres.
0.2
8, each number is a fifth of the last.
8*5 = 40 8*50 = 400 8*500 = 4000 and 8*5000 = 40,000
The factors of 5000 are: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, 625, 1000, 1250, 2500, 5000.
The factors of 5000 are: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, 625, 1000, 1250, 2500, 5000
1×5000 2×2500 4×1250 5×1000 8×625 10×500 20×250 25×200 40×125 50×100
8 x 5000 = 8 x 5 x 1000 = 40 x 1000 = 40000
800/40=200 The answer is 200.
5000+200+30+8=5238
405208 = 400000 + 5000 + 200 + 8
0.025
8, 40 and 200
40, 80, 120, 160, 200 +40 . . .
