On the checkerboard, 4/10 of the pieces left are red. What fraction of the pieces left are black? Write the equation.​
Alexeev081 [22]

Answer:

The fraction of black pieces left is \frac{6}{10}

Step-by-step explanation:

Given as :

On the checkerboard , The fraction of red pieces left = \frac{4}{10}

Let The fraction of black pieces left                              = x

So, The fraction of black pieces left = x = 1 - \frac{4}{10}

Or,                                                          x = \frac{10-4}{10}

Or,                                                          x = \frac{6}{10}

Hence The fraction of black pieces left is \frac{6}{10}  Answer
