Answer:trueTrueFalseFalseStep-by-step explanation:a. The problem tells me that for every 3 parts of red paint, I have 8 parts of yellow paint. To find the ratio of 1 part of yellow paint I can write the following statementFor 8 parts of yellow paint ------------ 3 parts of red paint 1 part of yellow paint ------------- xSo [tex]x=\frac{1 part of yellow paint * 3 parts of red paint }{8 parts of yellow paint}[/tex][tex]x= \frac{3}{8} parts of red paint[/tex]b, I have the following relationship3 parts of red paint ----- 8 parts of yellow paintIf I multiply the entire expression by 3 I have left3 * 3 parts of red paint -------- 8 * 3 parts of yellow paintSo9 parts of red paint ---------- 24 parts of yellow paintc.I have the same relationship3 parts of red paint ----- 8 parts of yellow paintIf I multiply the entire expression by 1/2 I have left3/2 parts of red paint -------- 8/2 parts of yellow paintSo3/2 parts of red paint ---------- 4 parts of yellow paintas 3/2 is different from 10, then the approach is falsed. observing the relation of part a,For 3 parts of red paint ------------ 8 parts of yellow paint 1 part of red paint ------------- xSo [tex]x=\frac{1 part of red paint * 8 parts of yellow paint }{3 parts of red paint}[/tex][tex]x= \frac{8}{3} parts of yellow paint[/tex] that is different than 3/8 parts of yellow paint, then the approach is false
