Question

2 1⁄100 kilometers = decimeters

Answer 1

`\large\boxed{2(1)/(100)\ kilometers=20100\ decimeters}`

Explanation:

`PREFIXES\\\\mega\ (M)=10^6\\\\kilo\ (k)=10^3\\\\hecto\ (h)=10^2\\\\deko\ (da)=10\\\\decy\ (d)=10^(-1)=0.01\\\\centi\ (c)=10^(-2)=0.01\\\\mili\ (m)=10^(-3)=0.001\\\\mikro\ (\mu)=10^(-6)=0.000001`

`2(1)/(100)=2.01\\\\2(1)/(100)\ km=2.01\ km=2.01\cdot10000\ dm=20100\ dm\\\\1\ kilometers=10000\ decimeters`

Answer 2

20100 decimeters

Explanation:

1 kilometer=10,000 decimeters

2 1/100=201/100

201/100*10,000=20100
