$$\frac=\frac$$ A proportion is read as "x is to y as z is to w" $$\frac=\frac \: where\: y,w\neq 0$$ If one number in a proportion is unknown you can find that number by solving the proportion.so you need twice as much of everything to keep the ratio.Here is the solution: And the ratio 2: is the same as 1:2:6 (because they show the same relative sizes) So the answer is: add 2 buckets of Cement and 4 buckets of Sand.I would recommend these exercise for 6th grade, 7th grade, and 8th grade math students.Solving Proportions Worksheet 1 (Integers) - This 9 problem worksheet features proportions that represent real-life situations where you will have to calculate the unit rate.
