There is a problem in today's math homework to weigh a pair of shoes. So I went to my mother and asked for a scale. Mom said she didn't have weighing scale. What shall we do? However, as the saying goes, "Nothing is difficult in the world". I think there must be a way.

So, I used my clever brain and came up with a homemade balance.

I cut off the paper covers of the empty moon cake box piece by piece, brought transparent folding tape, folded one of the paper covers into a regular triangle and put it on the table. Another piece of paper is made into the left and right disks of the balance and placed on the triangle in a balanced way. Then find something with weight at home as a weight. For example, my mother bought new toothpaste and lipstick with120g, 40g,18g and 3.5g..

Both have grams.

I'm very excited to say that the shoe activity has started. I put the shoes on the left side of the homemade balance and the "weight of goods" on the right side. It is best to balance the weight on both sides. Then the sum of the weights is the weight of my shoes. Exactly 86 grams. Hard work pays off! I finally finished my math homework. Mom praised me when she found out.

He also joked with me: "In ancient times, there was a clever Cao Chong as an elephant, but now there is a clever Han Han as a shoe!"

Say that finish, everyone laughed.

It turns out that there are scales everywhere in life!
