How do you express a fraction in simplest form?

divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers).

Step-by-step explanation:

Simplifying! Through reduction, and converting fractions into complex numbers

Step-by-step explanation: With a fraction of 25/5, you can reduce the fraction by dividing the numerator and the denominator by a factor of 5, simplifying it to 1/5, which is equivalent to 25/5.

With a fraction of 3/2 you can simplify it by converting it into a complex number. 3/2 can be converted into 1 and 1/2, because 3/2 or 3 divided by 2, is equal to 1.5, or 1 and 1/2.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
