Anna is 5 years old.
her mother is 33years old.
In how many years' time will her mother's age be 5 times her age?
The age of the mother over Anna is:
33 - 5 = 28 ( year old)
Anna's age when her mother is 5 times older is:
28:(5-1) = 7 (year old)
The number of years that the mother is 5 times older than Anna is:
7 - 5 = 2(year)
The difference in ages of mother and daughter is:
33 - 5 = 28 (age )
Mother's age is 5 times more than her son's age => Mother's age = \(\frac{5}{4}\) Age difference.
Mother's age at that time was:
28 x = 35 (age )
Then and now:
35 - 33 = 2 (years)

Emily is 3 years younger than her brother. Her father’s age is four times her brother’s age and 33 years older than Emily. How old is her brother?
Ta có: Anh trai hơn Emily 3 tuổi, bố hơn Emily 33 tuổi. Suy ra: Bố hơn anh trai số tuổi là: 33 - 3 = 30 (tuổi)
Tuổi bố gấp bốn lần tuổi anh trai. Suy ra: Hiệu số phần bằng nhau là: 4 - 1 = 3 (phần)
Suy ra: Tuổi anh trai là: 30 : 3 = 10 (tuổi)

Malanie is 8 years old. She asked her uncel about his age. Her uncel repied " When your reach my age, I will be 38 years old". How old is her uncel?
nam is 12 years old. his father is 52 years old. how many years ago his father's age five times his age?
The difference in ages of father and Nam is :
52 - 12 = 40 ( ages )
Since the age difference does not change over time, when the age of the father is 5 times the age of Nam, the age difference of the father and Nam is still 40 years old.
We have a diagram when the father's age is 5 times the age of Nam
Nam's age : |----------|
Father's age : |----------|----------|----------|----------|----------|
age difference is 40
Nam's age when his father's age is 5 times his age is:
40 : ( 5 - 1 ) x 1 = 10 ( ages)
Father's age is 5 times more than Nam's age in previous years is :
12 - 10 = 2 ( years ago )
answer:......

Hiệu số tuổi của 2 bố con hiện nay là :
52 - 12 = 40 ( tuổi )
Vì hiệu số tuổi không thay đổi theo thời gian nên khi tuổi bố gấp tuổi Nam 5 lần thì hiệu số tuổi của 2 bố con vẫn là 40 tuổi
Ta có sơ đồ khi tuổi bố gấp 5 lần tuổi Nam :
Tuổi Nam : |----------|
Tuổi bố : |----------|-----------|-----------|-----------|----------|
Hiệu số tuổi là 40 tuổi
Tuổi Nam khi đó là :
40 : ( 5 - 1 ) x 1 = 10 ( tuổi )
Tuổi bố gấp 5 lần tuổi Nam cách đây số năm là :
12 - 10 = 2 ( năm trước )
