Math: A small packet of fruit juice granules is brewed into a 5% beverage with 2 10g boiling water. How many grams are there in this packet of juice granules?
Suppose this packet of juice particles has x grams. According to the meaning of the question, the equation is as follows:
x÷(2 10+x)=5%
x=5%×(2 10+x)
x-5%x=5%×2 10
95%x= 10.5
X is approximately equal to 1 1.05.
That is to say, this packet of fruit juice granules has11.05g.
