Find the product 1.9(8.43) ! what does this mean? ?

If a number is besides each other (you'll know because of the brackets), then it means to multiply.

So this question is basically saying: 1.9 x 8.43

You can then use my strategy (which I don't know the name of) to answer this.

1.9 x 8.43 ---(Take away the decimal)---> 19 x 843

Then times the hardest number with the easiest one. (I'm rounding so it's easier)

843 x 20 = 1686
1686 - 84.3 = 1601.7 = 843 x 19

Then, however decimal places there was, add it to the answer.

1.9 x 8.43 has 3 decimal places, so,

16.017 is the answer.
