Question

Melisa used 0.6kg of red sand to make a mural on the wall. She added 250g of blue sand to it. Finally she added 500g of white sand to half of the mixture. Find the mass of the mixture that has white sand in it.
Express your answer in kilogram

Answer 1

06 kg of red + 250 g of blue
= 1100 g of mixed sand

1/2 of that is 550g
she adds 500 g of white to that, so
total stuff with white sand in it is 1050 g or 1.05 kg
