Given number is 78/14.
We have to find two whole numbers between which given number 78/14 lies.
Let's convert that into mixed fraction.
To do that we divide 78 by 14 to find the quotient.
We see that 14 goes 5 times into 78 and leaves remainder of 8.
So we can rewrite 78/14 as [tex] 5\frac{8}{14} [/tex].
[tex] 5\frac{8}{14} [/tex] means little more than 5 but less than 6.
So required two whole numbers are 5 and 6.
