Mr. Patrol is building a small fence around a garden. He purchased a piece of wood that's 8 1/2 feet long. Is each slat is going to be 2 1/3 feet long, how many full pieces can he make from the piece of wood? What he did: 8 1/2 divided by 2 1/2=16/2 x 7x3= 112/6=18 2/3. What was the error? What is the right solution?

Well first he can only make 3 full pieces of wood. The correct way would be dividing 8 1/2 by 2 1/3 to get 51/14, simplifed would be 3 9/14 and sinc e only full pieces its 3.  The thing she did wrong was when dividing she converted the mixed fraction wrong when converting it into an improper. 8 1/2 converts to 17/2 not 16/2. 16/2 doesn’t make sense becuase if you covert it back you’d only get 8, theres still a 1/2 in there too, the 1/2 doesn’t just disappears. You gotta multiply the denominator by the whole number then ADD the numerator to it to make the numeratorfor the improper fraction.

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
