Answer 1

Option c : 9 is the answer.

Explanation:

The expression is $1.2-(-7.8)$

We need to determine the subtracted value of the expression.

From the expression we can see that the expression contains two negative signs.

To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.

This means $(-) *(-) = +$

Thus, the expression can be written as

$1.2+7.8$

Adding the two numbers, we get,

$1.2+7.8=9$

Thus, the value of the expression is 9.

Hence, Option c is the correct answer.
