2 2/5
Step-by-step explanation:
-1 3/5 ÷ -2/3
First change the mixed number to an improper fraction
1 3/5 = (5*1 +3)/5 = 8/5
-8/5 ÷ -2/3
Copy dot flip
-8/5 * -3/2
Multiply the numerators then the denominators
24/10
Dividing the top and bottom by 2
12/5
Changing this back to a mixed number
10/5 +2/5
2 + 2/5
2 2/5

Pls mark Brainliest.
12/5 or 2 2/5 is the answer.
Step-by-step explanation:
-1 3/5 divided by -2/3.
First, we must turn the mixed fraction into an improper fraction so we are able to perform operations without the hassle of an extra whole.
-1 3/5 = -8/5
Now let's divide. Division is the same as multiplying the dividend by the reciprocal of the divisor. The divisor is the latter, or the number we are dividing the other number by, i.e. -2/3.
The reciprocal of -2/3 is -3/2.
Now let's multiply.
-8/5 * -3/2 = 24/10, which simplifies into 12/5.
12/5 or 2 2/5 is the answer.
