Question

What is six and one half divided by five

Answer 1

First you must transform the mixed number to the improper fraction

`6(1)/(2)=(6\cdot2+1)/(2)=(13)/(2)`

Divide by a some number is the same as multiplying by the reciprocal.

The reciprocal of 5 is
`(1)/(5)`.

Therefore we have:

`6(1)/(2):5=(13)/(2)\cdot(1)/(5)=(13\cdot1)/(2\cdot5)=(13)/(10)=1(3)/(10)=1.3`
