Question

If a/4=b/7, what is the value of a/b ?

Answer 1

4/7

Explanation:

If you multiply both sides of the equation you get:

7a = 4b

Divide by 7 on both sides

`a=(4b)/(7)`

Divide by b on both sides

`(a)/(b) = (4)/(7)`

Answer 2

`\frac {a}{b} = \frac {4}{7}`

Explanation:

Step 1: Multiply both sides by 4

`(a)/(4) = (b)/(7)`

`(a)/(4) * 4 = (b)/(7) * 4`

`a = (4b)/(7)`

Step 2: Divide both sides by 4

`\frac {a}{b} = \frac {(4b)/(7)} {b}`

`\frac {a}{b} = \frac {4}{7}`

Answer:
`\frac {a}{b} = \frac {4}{7}`
