0.15 * 0.3 ​

Question

`0.15 * 0.3`
​

Answer 1

Answer: -0.15

Explanation:

0.15=x0.3

We move all terms to the left:

0.15-(x0.3)=0

We add all the numbers together, and all the variables

-(+x0.3)+0.15=0

We get rid of parentheses

-x0.3+0.15=0

We move all terms containing x to the left, all other terms to the right

-x0.3=-0.15

x=-0.15/1

x=-0.15
