answer:
7.49 x 105 mm
0.45 miles
885 yards
34500 inches
reason:
I converted all the measurements to inches.
First, I multiplied 7.49x105 to get 786.45mm
Then, I divided it by 25.4 to get about 30.92 inches
Next, I converted 0.45 miles to inches by multiplying it by 63,360 to get 28,512 inches
For the yards, I took 885 and multiplied it by 36 to get 31,860 inches
Since the last one was already in inches, all I needed to do was put them in order from least to greatest
