1.704

Asemmisa {{asɛmmisaAhyɛnsode}}

What happens to the decimal point of the original number when you multiply it by 1/100? Why do you think that is? Explain your reasoning.

Asemmisa {{asɛmmisaAhyɛnsode}}

Which expression has the same value as (0.06) \cdot (0.154)? Select all that apply.

6 \cdot 1/100 \cdot 154 \cdot 1/1,000

6 \cdot 154 \cdot 1/100,000

6 \cdot (0.1) \cdot 154 \cdot (0.01)

6 \cdot 154 \cdot (0.00001)

0.00924

Calculate the value of each expression by writing the decimal factors as fractions, then writing their product as a decimal. Show your reasoning.
