1 hour = 90 + 120 = 210 miles apart

What is eight over nine divided by two over three equal to?
Rom4ik [11]

Answer:

4/3

Step-by-step explanation:

Let the fractions be A and B.

Given the following data;

Fraction A = 8/9

Fraction B = 2/3

\frac {Fraction A}{Fraction B} =  \frac {\frac {8}{9}} {\frac {2}{3}}

\frac {Fraction A}{Fraction B} =  \frac {8}{9} * \frac {3}{2}

\frac {Fraction A}{Fraction B} = \frac {24}{18}

Dividing by 6, we have;

\frac {Fraction A}{Fraction B} = 4/3

The result of the multiplication of a positive 2 and a negative 3 is;

           2 x -3 = -6 ,  gives a negative 6.

So the number line should scale to accommodate the operands and the result, which is from negative 7 to positive 3, in the option given.
