To compare expression A (56×250) and expression B ((13×250) + (12×250)), we can first observe that expression B can be simplified:
Expression B can be factored as: (13×250) + (12×250) = (13 + 12) × 250 = 25 × 250.
Now we can clearly see that we are comparing 56×250 with 25×250.
Since 56 is greater than 25, we conclude that:
Expression A is greater than expression B.
