Which statement compares the two numbers correctly?

slamgirl [31]

Answer:

Step-by-step explanation:

So, we have-

(6 x .1) + (3 x .01) + (2 x .001)

So, we will solve inside of the parenthesis first.

6 x .1 = .6

So, we got that settled next-

3 x .01 = .03

We got that settled last-

2 x .001 = .002

Lastly, we add them all.

.6 + .03 + .002 = .632

Now we compare.

.632 > .629

So, there is your answer!

Hope this helps!
