Multiplication and Division of Signed Mumbers: Dividing numbers with different signs

$(+10):(-5)=$

Due to the fact that we are dividing a positive number by a negative number, the result must be a negative number:

$+:-=-$

Therefore:

$-(10:5)=-2$

$-2$

$(+24):(-0.4)=$

Since we are dividing a positive number by a negative number, the result will necessarily be a negative number:

$+:-=-$

First, let's convert 0.4 to a simple fraction:

$0.4=\frac{4}{10}$

Now we have the problem:

$-(24:\frac{4}{10})=$

Let's convert the division to multiplication, remembering to switch the numerator and denominator:

$-(24\times\frac{10}{4})=$

We'll simplify by 4 and get:

$-(6\times10)=-6\times10=-60$

$-60$

$(+3):(-0.05)=$

Since we are dividing a positive number by a negative number, the result will necessarily be a negative number:

$+:-=-$

First, let's convert 0.05 to a simple fraction:

$-0.05=-\frac{5}{100}$

Now we have the problem:

$-(3:\frac{5}{100})=$

Let's convert the division to multiplication, remembering to switch the numerator and denominator:

$-(3\times\frac{100}{5})=$

Let's continue solving the fraction problem:

$-(3\times20)=-60$

$-60$

$(+0.9):(-0.15)=$

$-6$
