Answer:
3/10
Step-by-step explanation:
- add 7+4+6+3=20
- the take how many times both coins landed on heads which is 6 and put the 6 over 20
- then divide by 2 because 2 can go into both 6 and 20
- and you end up with 3/10 which you can't simplify any more.

Ratio of complement of x : supplement of x
2 : 5
⇒ 2 times the supplement of x will be equal to 5 times the complement of x
5(90 - x) = 2 (180 - x)
450 - 5x = 360 - 2x
5x - 2x = 450 - 360
3x = 90
x = 30°
Complement of x = 90 - x = 90 - 30 = 60
Supplement of x = 180 - x = 180 - 30 = 150
Ratio:
60 : 150
60 ÷ 30 : 150 ÷ 30
2 : 5 (checked)
