Question

at Cassie's Cashew Shoppe, a sign says, "Today only :20% off anything ." Maribel realizes that she has a coupon for 1/5 off the price of anything in the shop.Which discount should she use, the 20%-off deal or the 1/5-off coupon? Does it matter? Explain.

Answer 1

It doesn't matter, both of them are the same.

1/5 = 20/100, or 20%.
