Answer:
2 5 /14
Step-by-step explanation:
−10 2/7 ÷ (−4 4/11)
Change to improper fractions
−10 2/7 = - (7* 10+2)/7 =-72/7
-4 4/11 = -( 11*4+4) = -48/11
-72/7 ÷ -48/11
Copy dot flip
-72/7 * -11/48
Canceling an 8 from the top left and the bottom right
-9/7 * -11/6
Canceling a 3 from the top left and the bottom right
-3/7 * -11/2
33/14
Now we change it back to a mixed number
14 goes into 33 2 times 2*14 = 28
33-28 = 5 this goes over the denominator
2 5 /14
