Week 331 (26th January 2024)

Gavin likes to make a protein shake each morning.  

To prepare his protein shake, Gavin combines three containers of protein powder with a fourth container containing a mixture of: 

15% chia seeds  

85% protein powder 

All the containers have the same volume.  

What percentage of Gavin’s protein shake is chia seeds? 


¼ of the protein shake is made up of the 4th container.  

To find 15% of the ¼ we can multiply ¼ by 0.15 

¼ x 0.15 = 0.0375, then to find as a percentage we multiply by 100 

0.0375 x 100 = 3.75% 

Answer: 3.75%
