Answer 1

Step-by-step explanation:

Total numbers of balls = 180

No of black balls =

1 out of 5 = x out of 180

1/5 = x/180

x/180 = 1/5

x = (1×180)/5

x = 36

No. of black balls = 36

No. of Red balls =

1 out of 3 = y out of 180

1/3 = y/180

y/180 = 1/3

y = (1×180)/3

y = 60

No. of Red balls = 60
