Answer:
(6 x 0.1) + (2 x 0.01) + (7 x 0.001)
Explanation:
Let's use the process of elimination.
(6 x 1) equals to 6, and 6 would be located in the ones value.
(6 x 0.1) equals to 0.6, meaning 6 would be in the tens places.
In our last two remaining options, we will try one more for the hundredths.
(2 x 0.001) = 0.002. The 2 here is located in the thousandths, not the hundredths.
(2 x 0.01) = 0.02, the 2 is located in the hundredths, it is correct, and the only one left.
