Interesting Mathematics in Grade Two —— The story of Bajie selling vinegar

Bajie opened a small grocery store. One day, the little monkey came to make a catty of vinegar for his family. The little macaque came to Uncle Shi's shop and shouted, "Uncle Shi, jealous!" " "

Bajie asked the little macaque how much vinegar he played. The little macaque said, "Not much, just one or two."

Pig was surprised and asked, "What's the use of vinegar?" The little macaque said, "Of course!" Pig asked again, "Is one or two enough?" The little monkey said, "Not enough, let's play one or two more!" " "

Pig asked again, "Two taels is not much?" The little monkey said, "Let's play again." Bajie hit once or twice again. The little monkey said, "Give me one or two, and then give me one or two ..." In this way, the little monkey made twelve ounces of vinegar, which is a catty of vinegar.

After drinking vinegar, the pig said, "* * * A catty of vinegar is eighty cents." The little macaque unhurriedly took out eighty cents and gave it to Uncle Bajie. Pig took the money and said, "No kidding, it's still 4 cents short!" The little macaque asked, "Uncle Shi, how much is a cup of vinegar?" "

Pig Bajie said, "Of course, one or two vinegar is 80 cents and four cents will be given away. Charge 8 cents. " The little monkey said, "So, one vinegar or two is 8 cents." "Of course," Pig said. The little macaque added, "Twelve ounces of vinegar is eighty cents!" "

Pig said, "It's accurate." The little monkey said, "I gave you eighty cents." How can you say that you still need 4 cents? " Bajie was speechless, lost another 40 cents, and watched the little macaque go away with vinegar.
