Question #2ed77

Answer 1

Depends on what you meant to type. See explanation

Explanation:

Assuming you meant: `1/(3b)=5`
`1=5(3b)`
`1/5=3b`
`0.2/3=b` (since `1\div5=0.20`)
`b\approx0.067`

Assuming you meant: `1/3b=5`
`b=5\div(1/3)`
`b=5xx(3/1)` fraction division rule: multiply by reciprocal
`b=5xx3=15`
