Unit rate - production in one second

20 bottles - 1 min

1 min - 60 seconds

20 bottles - 60 seconds

20 : 60 : : x : 1

20 = 60x

x = 20 / 60

x = 1/3

1/3 rd bottle is produced in one second

Hope helps!

weqwewe [10]

Answer:

144 boys and 384 girls

Step-by-step explanation:

8 girls to every 3 boys. You can make an equation to solve this: 8x + 3x = 528. 528 = 11x. Then divide 528 by 11 to get 48. x=48. 8(48) = 384 girls. 3(48) = 144 boys.
