Choose all of the expressions that are equivalent to 2 1/2 divide by 1 2/6 A. 5/2 x 6/8
B. 2/5 x 6/8
C.1 2/6 divided by 2 1/2
D.5/2 divided by 8/6

A

Step-by-step explanation:

5/2 x 6/8 is thecorrect answer

A and D I think

Step-by-step explanation:

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

9 x 8 divided by (5-3)=36
