Third, solve the problem: 1. Dissolve 25g of sugar in100g of water. What is the sugar content of sugar water?
The first thing to know is to divide sugar by syrup to get the sugar content.
The first thing to know is to divide sugar by syrup to get the sugar content.
Calculated sugar water: 100+25= 125 (g)
Sugar content: 25/ 125=0.2=20%
A: The sugar content is 20%.
3. The chemical fertilizer plant produced 3,700 tons of chemical fertilizer last year 10, of which the tonnage in the early stage was 2/3 of that in the middle stage and 4/5 in the late stage. How many tons of chemical fertilizer did the chemical fertilizer plant produce in the early stage? {Important process and description}
Mid-term = 3700 ÷ (2/3+1+4/5) =1500 tons.
Early stage = 1500×2/3= 1000 tons.
4. A set of furniture took 65,438+02 days, and it took 65,438+08 days for Master Liu to complete it. I've been here for a few days now, and the rest was completed by Master Liu due to illness, so it took 16 days to complete this set of furniture. Li Shifu did it for a few days first. {Important process and description}
Suppose: Li Shifu did it for x days first.
(x/ 12)+[( 16-x)/ 18]= 1
(3x+32-2x)/36= 1
X=4 (days)
Hope to adopt, thank you.
