Quizplus · Accepted Answer

When solving problems where you convert ratios/proportions to percentages, you first want to add the parts to get the whole. In this case, we have 2 parts water and 1 part rice. 2 + 1 = 3, so there are 3 total parts. Then we divide the part we are interested in (rice, which = 1) by the total number of parts (the whole, which = 3): ¹/₃ = 0.66 = 33% *Remember that the fraction line is a symbol for division. Therefore, when we see ¹/_3,we know that it means 1 ÷ 3.
