Simplify ratio
60 : 20

The answer is 3 : 1.

Step-by-step explanation:

In order to find the simpliest form, you have to find the common factor of 60 and 20 :

20 = 1×20, 2×10, 4×5

= 1, 2, 4, 5, 10, 20

60 = 1×60, 2×30, 3×20, 4×15, 5×12, 6×10

= 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The common factors between 60 and 40 is 2, 4, 5, 10 and 20 but you have to choose the greatest factor which is 20 so that you can simplify completely. You have to divide 20 to both sides :

60 : 20

= 60÷20 : 20÷20

= 3 : 1

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
