the first solution is 20% acid, and say we'll be using "x" liters, so how many liters of just acid are in it? well 20% of "x" or namely 0.2x. Likewise for the 60% acid solution, if we had "y" liters of it, the amount of only acid in it is 0.6y.
Which shows the best path to find the number of centimiters in 1 yard
1 answer:
For this case we have by definition that one yard equals 91.44 centimeters.
We propose a rule of three that allows you to find the number of centimeters in any number of yards:
1yd ------------> 91.44cm
x ------------> y
Where:
y: It is the number of centimeters
x: It is the number of yards.
Answer:
