Answer:

Part C: 0.467

Part D: 31

Step-by-step explanation:

Whenever we are multiplying or dividing two numbers with different significant figures, the final result attains the significant figures of a factor with the lowest significant figures.

Therefore. we compute


24.9*1.99/106.99

to get


0.4666258

Now, the lowest significant figures present in the factors is 3; therefore, rounding the above to 3 significant figures gives


0.467

Part D.

The lowest number of significant figures present in a factor is 2; therefore, we will round our final answer to 2 significant figures.

Now,


(2.200*10^6)/(7.0*10^4)=31.42857

Rounding to 2 significant figures gives


31

which is our answer!
