Answer 1

The answer is: " 18.856 " .
_______________________________________
Step-by-step explanation:
_______________________________________
Here is ONE method:
__________________
Given:
___________________

99.1
* 0.16
____________
= ?
_________________________
Here is one way to approach the problem—
(Note: Work is shown in this explanation; as dictated by the actual
question being asked.) ;
__________________________
→ Write problem as:
__________________________
991
* 16
_________ → and solve;
5946
+ 991
_________
15856 ;
_______________________________________________
Then, taking the number; "15856", we move the decimal; or "implied decimal point"; ending after the last digit, "6"; ; back 3 (THREE) spaces;
since the original problem is: "99.1 * 0.16 ; as such, we move the "implied decimal point" back "1 (ONE) space; to account for the fact that we used "991" in lieu of the actual value {"99.1"} ; and we move the "implied decimal point" back 2 (TWO) additional spaces''; to account for the fact that we used "16" in lieu of the actual value {"0.16"}.
______________________________________
→ As such, we take: " 15856." ; and move the "implied decimal point" ending after the number, "6"; back three spaces, to get: " 15.856 ".

Let us check our answer by using a calculator:
____________________________________________________
→ 99.1 * 0.16 =? 18.856 ?? ; Yes!

Answer 2

99.1
x0.16

6(1)=6
6(9)=54. Put down the 4 and carry the 5.
6(9)=54+5= 59.

You work in reverse, so our last number should be first and our first number last. So the first number is: 5946

Our next row, we put down a 0 and then continue.
1(1)=1
1(9)=9
1(1)=9

Our second number is 9910.

Add the two: 5946+9910=15856

Count the number lf decimal places. In this case, three. Move the decimal 3 places left: 15.856

I always double check using a calculator.
