Question

Divide 40x/64y by 5x/8y.

Answer 1

The correct answer option is C. 1.

Explanation:

We are to divide
`\frac { 4 0 x } { 6 4 y }` by
`\frac { 5 x } { 8 y }`.

Rewriting them as a fraction in whole:

`\frac { \frac { 4 0 x } { 6 4 y } } {\frac { 5 x } { 8 y } }`

Changing the division into multiplication by taking the reciprocal of the fraction in the denominator to get:

`\frac { 4 0 x } { 6 4 y }` ×
`(8y)/(5x)`

Cancelling out the like terms to get:
