Answer:
30.51
Step-by-step explanation:
We want to multiply
[tex]67.8 \times 0.45[/tex]
We convert to fraction and multiply.
[tex] \frac{678}{10} \times \frac{45}{100} [/tex]
[tex] \frac{30510}{1000} [/tex]
This is the same as
[tex]30510 \times {10}^{ - 3} [/tex]
We now move the decimal point back three times
[tex]30.510 [/tex]
Or
30.51
This is our final answer to the nearest hundredth.
