-
Each subtracts three years old, the father is 40 years old, and the daughter is 8 years old, exactly 20%.
-
I will answer it myself, and I hope for it.
Solution: Let the daughter's age be 20% of the father's before x, and the equation can be obtained:
43-x)×20%=11-x.,x=3;
A: Three years ago, my son was 20% of my father's age
-
Solution: Suppose the daughter's age was 20% of her father's before x.
43-x)*20%=11-x
x = 33 years ago, the daughter's age was 20% of her father's
-
Let x years ago, then the father is 43-x, then the daughter is 11-x, (43-x)*, you can calculate, x=3, is it okay? I don't know how to ask again.

Three years ago, Gozen. How many years ago, the age of the daughter was 20% of the father's, in other words, the father's age was 5 times that of the daughter. The age difference between the father and the daughter will not change, when the father's age is 5 times that of the daughter, the father's age is 4 times older than the daughter's age, and these 4 times is the age difference between the two, so the age of the daughter of the year is (43-11) (5-1) = 8 years old, this year's daughter is 11 years old, and the town is stupid and clear that the age of the daughter is 11-8 = 3 years ago is 20% of the father's.

3 years ago. At this time, a math equation problem can be set to x a few years ago, according to the equation of (43 x) 20 11-x according to the fact that the father is 43 years old and the daughter is 11 years old this year.
If x is equal to 3, then three years ago, the daughter's age was 20% of her father's slender hand.

Set x years ago, my daughter's age was 20% of that of my father, Yuming Wang's father
43-x) 20% = 11-x 20% approximate.
43-x)1 5=11-x Equation: Huaizhou on both sides of Zhenzi multiplies 543-x=11*5-5x shift.
5x-x=55-43
4x = 12x = 3 years.
A: 3 years ago, my daughter's age was 20% of her father's

3 years ago. Suppose the daughter's age before x was 20% of her father's, then there is 11-x=(43-x)*, and the solution is x=3. That is, three years ago, the daughter was 8 years old, the father was 40 years old, and the daughter was 20% of the father's age.

-
Three years ago, my daughter's age was 20 percent of her father's. Three years ago, my daughter was 8 years old and my father was 40 years old. 20 percent means 1 5Then 8 40 = 1 5
-
Set: Daughter's age x a few years ago.
11x = 43 times 20 percent
11x = approximately equal to 9].
x = 9 divided by 11
x is approximately equal to 1 year
-
Simple question: Just make an equation.
Just set x years ago, the daughter's age was the same as the father's.
-
Set x years ago, the daughter's age was 20% of the father's, from the title.
11-x)*5=43-x
55-5x=43-x
4x=12x=3
Three years ago, my daughter's age was 20% of her father's
