Are there any problems in this?
-3 1/5 / -2/3 = -4 4/5 Here is the work it showed. -3 1/5 / -4 4/5=-16/5 * -3/2=-8/5 * -3/1 = -24/5= -4/5
To me, I think there is something wrong in this the answer suppose to be positive, not negative. The only thing that I am not sure is where is the problem at
I see two things wrong.
First, a negative divided by a negative equals a positive.
Second, this isn't right.
-24/5= -4/5
Yeah, that's what I thought too. I keep on second guessing myself. Anyway thanks.
You're welcome.
The answer is 4 4/5
To find the problem in the given calculation, let's break down the steps:
Step 1: -3 1/5 ÷ -4 4/5
To divide mixed numbers, we convert them into improper fractions:
-3 1/5 = (-3 * 5 + 1) / 5 = -16/5
-4 4/5 = (-4 * 5 + 4) / 5 = -24/5
So, the expression becomes:
-16/5 ÷ -24/5
Step 2: Invert the second fraction and change the division operation to multiplication:
-16/5 * -5/24
Step 3: Simplify the multiplication operation by canceling out common factors:
-16/5 * -1/24 = 16/5 * 1/24 = 16/120
Step 4: Simplify the fraction:
16/120 = 4/30 = 2/15
Therefore, the correct answer is 2/15, not -4 4/5.
The mistake in the given calculations is in step 1. The conversion of -4 4/5 to an improper fraction is incorrect. It should be (-4 * 5 + 4) / 5 = -20/5 + 4/5 = -16/5, not -24/5. So, the correct calculation should be:
-3 1/5 ÷ -4 4/5 = -16/5 ÷ -16/5
When we perform the correct calculation, we get:
-16/5 ÷ -16/5 = (-16/5) * (-5/16) = 16/5 * 5/16 = 16/80 = 1/5 = 0.2
Therefore, the correct answer is 0.2 or 1/5.
