Answer:

129

Step-by-step explanation:

If you want it reduceable to a unit fraction, then the reciprocal would be equal to an integer. Make an equation, "(333+x)/77=y," and you see the positive side is just under 5, so you plug in "5 = y," and get 52 = x. That isn't a 3 digit number, so you plug in "6 = y," and get 129 = x.

Answer:

3 or 4

Step-by-step explanation:

77 has factors 7 and 11

To be reducible, the denominator must have one of these factors too

For the common factor to be 11:

77/3333

7/303

For the common factor to be 7:

Answer: 20 miles

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:

x^2 = a^2 + b^2

Where x is the hypotenuse of the triangle (in this case the distance between Dayton and Belleville) and a and b are the other sides.

Replacing with the values given:

x^2 = 16^2 + 12^2

x^2 = 256+144

x^2 = 400

x = √400

x = 20 miles
