Divide the 3-meter-long wire into 8 parts, each part is a fraction of the length of the wire, each part is a fraction of the length of the wire, and each part is a fraction of the length of the wire

Divide the 3-meter-long wire into 8 parts, each one is 1 / 8 of the wire, each one is 3 / 8 of the wire, and each one accounts for 1 / 8 of the total length

There is one black chess piece in each chess piece. How many black chess pieces account for
Each piece has one black piece. What percentage of the total number of black pieces? Who's going to save me~

Title: there is one black chess piece in each a chess piece. How many black chess pieces account for
So black pieces account for 1 / a of the total
For example: there is one black chess piece in every 10 pieces. What percentage of the total number of black chess pieces
Then the black pieces account for 1 / 10 of the total, that is, 1 / 10

There are a series of 96 colored lights, which are arranged in the order of three blue lights, two yellow lights and one red light. What percentage of the total number are the lights of various colors?

96 (3 + 2 + 1) = 16 (cup) 16 × 3 △ 96 = 1 / 2 (blue) 16 × 2 △ 96 = 1 / 3 (yellow) 16 △ 96 = 1 / 6 (red)

As shown in the figure on the right, there is one black chess piece in every three go pieces. How many black chess pieces account for the total number of flags?

4 * 3 = 12 4 / 12 = 1 / 3
