Answer 1

b= 15

Explanation:

Answer 2

b = 15

Explanation:

Solve for b:

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

Cross multiply:

`6(2)/(3)\cdot 4.8=1.2b\cdot 1(7)/(9)\\ \\(6\cdot 3+2)/(3)\cdot 4.8=1.2b\cdot (9+7)/(9)\\ \\(20)/(3)\cdot (48)/(10)=(12b)/(10)\cdot (16)/(9)\\ \\20\cdot 4=b\cdot (16)/(3)\\ \\5=b\cdot (1)/(3)\\ \\b=5\cdot 3\\ \\b=15`
