Can you help me with this math question to help my sister?
So, Peter starts out with X crops, which is 100% (by definition of what a 100% means). He the harvested 40% of X, leaving him with 60% of X. He then counts how much crops he still has to harvest and arrives at 150. This means he knows that 60% \times X = 150.Numerically, 60% is represented by the number .6, so we have:[math].6 \times X = 150[/math]Or [math]X = \frac{150}{.6} [/math]Simply putting that in a calculator will give you the total amount of crops (X, 100%). You then simply calculate X - 150 and you will get the number of crops harvested.
