Answer:
a) 10
b) 10000
c) 100
d) 1000
Step-by-step explanation:
With 0.80 × 10, we move the decimal up one place, so it equals 8.0 or 8
10000 × 0.002, we move the decimal up four places, so it equals 0020.0 or 20
0.04 × 100, we move the decimal up two places, so it equals 04.0 or 4
Lastly, 1000 × 0.5, we move the decimal up three places, so it equals 500.0 or 500
Using the powers of ten, we either move the decimal up or down according to the number of zeros.
