Question

Benjamin and his sister shared a largesandwich. Benjamin ate 3/5 of the sandwichand his sister ate 1/10 of the sandwich.Which is the best way to estimate howmuch more Benjamin ate than his sister?A. 1/2 - 0 = 1/2B. 1/2 - 1/2 = 0 C. 1 - 0 = 1D. All of the above

Answer 1

A.

`(1)/(2)-0=(1)/(2)`

Explanation:

We must subtract from the amount that Benjamin ate what his sister ate, like this:

`(3\cdot2)/(5\cdot2)-(1)/(10)=(6)/(10)-(1)/(10)=(5)/(10)=(1\cdot5)/(2\cdot5)=(1)/(2)`

So that's the difference between both, the best way to represent then would be:

`(1)/(2)-0=(1)/(2)`
