Answer:
The fraction of black pieces left is [tex]\frac{6}{10}[/tex]
Step-by-step explanation:
Given as :
On the checkerboard , The fraction of red pieces left = [tex]\frac{4}{10}[/tex]
Let The fraction of black pieces left = x
So, The fraction of black pieces left = x = 1 - [tex]\frac{4}{10}[/tex]
Or, x = [tex]\frac{10-4}{10}[/tex]
Or, x = [tex]\frac{6}{10}[/tex]
Hence The fraction of black pieces left is [tex]\frac{6}{10}[/tex] Answer
