Question

1.34 x-67.8 =I need help

Answer 1

-90.852

Explanation

1.34*-67.8

Step 1

count the number of digits after the dot in each number

$\begin{gathered} 1.34\text{ }\Rightarrow\text{ 2 digits after the dot} \\ 67.8\Rightarrow1\text{ digit} \end{gathered}$

total = 2+1= 3 digits after the points.

Step 2

eliminate the dots and do the multiplication

$\begin{gathered} 134\cdot-678 \\ +\text{ multiplied by - is =-, then} \\ 134\cdot-678=-90852 \end{gathered}$

Step 3

go to the last number of the result(rigth side) and move those e spaces(the total count of digits in step 1) from right to left, and mark the point) it is

$\begin{gathered} \text{number of spaces to move= 3} \\ \text{result= -90852} \\ \text{then} \\ -90.852 \end{gathered}$

so, the answer is -90.852
