greatest common factor is the hightest possible number which can divide all the three , 15, 30 and 45 all are divisble by 15 so the gcf is 15 :)
is the answer is 3.99
Does the dot"." represents multiplication ? if so then
-7-(5x7) = -7 - (-35)
'''''''' = -7 + 35
'''''''' = 28
= -7 + 5.7
I found Salman's response to this post intriguing.
We should clearly be aware of the fact that there are different ways to represent decimal numbers.
In many English speaking countries like US, Canada, UK, and Australia, the "dot" is used as a decimal place indicator, while a large portion of the rest of the world uses the comma to show where the decimal place is.
Just an observations for what it is worth.
