Question

You have to write 1/2 page for an assignment. You write 1/5 page. How many pages do you have left to write ?

Answer 1

To find the number of missing pages:

`(1)/(2)-(1)/(5)=`

rewriting the expression as homogeneous fractions:

`(1)/(2)*(5)/(5)-(1)/(5)*(2)/(2)=`

simplifying it:

`(5)/(10)-(2)/(10)=(3)/(10)`

ANSWER

you have left 3/10 page.
