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 3 parts flour and 1 part water. 3 + 1 = 4, so there are 4 total parts. Then we divide the part we are interested in by the total number of parts (the whole): ¾ = 0.75 = 75% *Remember that the fraction line is a symbol for division. Therefore, when we see ³/_4,we know that it means 3 ÷ 4.
