We know the product will have 5 decimal places. Multiply 0.004 and 0.73,
ignoring the decimal points. In other words, just multiply 4 and 73 to
get 292. Then move the decimal point left 5 places to the left to get
the correct final answer. (Remember, we only move the decimal place to
the right during multiplication when we're multiplying by a power of 10.
No power of 10 here. We're looking pretty powerless.) | |
