Question

A painter mixes 6 parts red paint and 8 parts yellow to make dark orange paint. Which equation can the painter use to calculate the amount of red paint, R, that is needed to mix with a given amount with yellow paint, Y? A. R= 6/8 = Y, B. R=6/8- Y, C. R=3/4y, D. R= 4/3Y.

Answer 1

Red : Yellow
   6   :  8
 (÷6)  (÷6)
   1   : 8/6 
   1   : 4/3

therefore, R = 4/3Y

Answer: R = 4/3Y
