Write the ratio in the simplest form.
45 : 15
a. 9 : 3
b. 3 : 1
c. 1 : 3
d. 4 : 1

Simplest form of the ration 45 :15 can be solved by dividing the both number by there greatest common factor. So the greatest common factor of 45 = (15 x3 and 15 = (15 x 1) so 15 is the greatest common factor. 45 /15 = 3 and 15/15 =1 so the ratio 3 :1

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
