Question

Linda is sending out cards.If envelopes come in boxes of 25 and stamps come in packs of 10,what is the least number of stamps and envelopes she can buy to get one stamp for each envelope

I think Linda would buy 2 boxes of envelopes and 5 packs of stamps. 
2*25=50
10*5=50
Then she'd have one stamp for every envelope
