72 = 2 * 2* 2 * 3 * 3
120 = 2 * 2 * 2 * 3 * 5
The greatest common factor (GCF) would be gotten from the factors common to both 72 and 120.
The common = 2 * 2 * 2 = 8
The GCF = 8
<em>your answer to the question would be </em><u><em>18.9 ≈ 19ft</em></u>
Greg has walked
miles
<em><u>Solution:</u></em>
Given that, Greg’s house is 0.8 miles from the library
Distance between house and library = 0.8 miles
Greg has walked
of the distance
Therefore,
Distance walked =
of the distance between house and library
Here "of" means multiplication
Thus we get,


Thus Greg has walked
miles
6.4 x 10 cubed aka the 3 is on the top right of the 10
It's about 83.544 sorry if I get it wrong I'm really sorry I add
