How would I go about dividing. -20 divided by (-2 1/2)
-20 / (-2 1/2)
-20 / (-5/2)
-20 * (-2/5) = 40/5 = 8
Or--
-20 / -2.5 = 8
To divide -20 by (-2 1/2), you can follow these steps:
Step 1: Convert the mixed number (-2 1/2) into an improper fraction.
To convert a mixed number to an improper fraction, multiply the whole number part by the denominator and add the numerator. In this case: (-2 * 2) + 1 = -3. So, (-2 1/2) is equivalent to -5/2.
Step 2: Divide -20 by -5/2.
To divide by a fraction, you can multiply by its reciprocal (flipping the numerator and denominator). So, you need to multiply -20 by the reciprocal of -5/2.
The reciprocal of -5/2 can be found by swapping the numerator and denominator, which gives us -2/5.
Step 3: Multiply -20 by -2/5.
Multiply the numerators (-20 * -2) and the denominators (1 * 5). The result is the answer to the division: 40/5, which simplifies to 8.
Therefore, -20 divided by (-2 1/2) is equal to -8.
