Answer:
Step-by-step explanation:
This question is about the benefits of estimation.
1300/13 is easy and results in 100.
1287/13 can be approximated by 1300/13: 1287/13 ≈ 100.
Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.
So: 1287/13 = 1300 - 13 = 1287. A nice bit of mental math!
First do 70+24=94
Then do 180-94=86
Next 86+54=140
Then 180-140=40
Next 40+80=120
Lastly 180-120=60
X=60
Its independent because it does not depend on the answer before
