Question

I am supposed to write 'Half of the difference between a and b, where a is bigger than b' as an expression but I don't understand how. Can I please have an explanation on how and why?

Answer 1

Answer:  $\bold{\dfrac{1}{2}(a-b)}$

Step-by-step explanation:

"half" means   $\dfrac{1}{2}$

"of" means multiply

"difference" means subtract

half       of       the difference between a and b

 $\dfrac{1}{2}$          ×       (                                        a   -    b )

$\large\boxed{\dfrac{1}{2}(a-b)}$
