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

ANSWER:

A.

$\frac{1}{2}-0=\frac{1}{2}$

STEP-BY-STEP EXPLANATION:

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

$\frac{3\cdot2}{5\cdot2}-\frac{1}{10}=\frac{6}{10}-\frac{1}{10}=\frac{5}{10}=\frac{1\cdot5}{2\cdot5}=\frac{1}{2}$

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

$\frac{1}{2}-0=\frac{1}{2}$
