Answer:
18/23
18 goes in the green box
Step-by-step explanation:
1. Convert each number into an improper fraction; multiply the denominator by the whole number and add to the numerator.
First fraction:
5×(-1) = -5
-5 + (-4) = -9
Second fraction:
10×(-2) = -20
-20 + (-3) = -23
-9/5 ÷ -23/10 = ?/?
2. Change the problem to multiplication by changing the second fraction to its reciprocal.
-9/5 × -10/23 = ?/?
3. Multiply the two fractions together.
-9/5 × -10/23 = 90/115
4. Simplify by the greatest common factor of the numerator and denominator.
90/5 = 18
115/5 = 23
This gives you 18/23.
