Please help me solve this ASAP!

Answer 1

Explanation:

`(4.8)/(1 (7)/(9) ) = (1.2b) / 6 (2)/(3)`

`( (48)/(10) )/( (16)/(9) ) = (12b)/(10) / (20)/(3)`

`(48 * 9)/(10 * 16) = (12b)/(10) * (3)/(20)`

`(432)/(160) = (36b)/(200)`

`432 * 200 = 160 * 36b`

`86400 = 5760b`

`b = (86400)/(5760)`

`b = 15`
