Xiao Ming is 12 years old this year, and his father is 39 years old this year, and his father is how

Xiao Ming is 12 years old this year, and his father is 39 years old this year, and his father is how much older than Xiao Ming in 3 years

Thinking: Xiao Ming is 12 years old this year, Dad is 39 years old this year, and Dad is 39-12=27 years older than Xiao Ming this year. Three years later, Xiao Ming was 15 years old, his father was 42 years old, and 42-15 = 27 years old.

How old Xiao Ming is, how old will Xiao Ming's father be, so no matter how many years later, his father will be 27 years older than Xiao Ming. Equation:

27 (years old) Xiao Ming is 12 years old this year, his father is 39 years old this year, and his father is 27 years older than Xiao Ming in 3 years.

27 years old. Pay attention to this kind of question, after three years, Xiao Ming will rise by 3 years, and Dad will also rise by 3 years. So the gap between the two is not going to change. Today's dad is older than Xiao Ming: 39-12=27 years old, and three years later he is still 27 years older.

27 years old. Because the age of the two is growing at the same time, no matter how many years have passed, their age gap is: 39-12 = 27 (years old), that is, 3 years later, Dad is 27 years older than Xiao Ming.

27 years old.

When Xiao Ming was 12 years old, his father was 39 years old, so his father was 27 years older than Xiao Ming.

Three years later, Xiao Ming was 15 years old and his father was 42 years old. So Xiao Ming is 27 years younger than his father.

Solution, Xiao Ming's age after 3 years, 12 + 3 = 15 years old.

Dad's age after 3 years, 39 + 3 = 42 years old.

So after 3 years, Dad is older than Xiao Ming, 42-15=27 years old.

A, 3 years later, my father is 27 years older than Xiao Ming.

Three years later. Xiao Ming's age is: 12+3=15 (years).

Daddy's age: 39 + 3 = 42 (years).

Dad is older than Xiao Ming: 42-15 = 27 (years old).

From this question, we can also draw such a conclusion: how many years are the two different this year, and in a few years, the two will be a few years apart. The age difference is the same.

This year, Dad is 27 years older than Xiao Ming, 39-12=27, and he will still be 27 years old three years later, because Dad is getting older, Xiao Ming is getting older, so after 3 years, Dad is 42, Xiao Ming is 15, 42-15=27

Xiao Ming is 12 years old this year, and his father is 39 years old this year, a difference of 27 years, and his father is 27 years older than Xiao Ming after 3 years.

Because 3 years later, Xiao Ming is 15 years old and his father is 42 years old.

Analysis: No matter how old Dad is older than Xiao Ming in a few years, it will be the same.

Solution: 39-12=27 (years).

A, 3 years later, my father is 27 years older than Xiao Ming.

How much older is the father than Xiao Ming after 3 years, if you calculate how much older the father is than the current Xiao Ming after three years, it is 39 + 3-12 30 years old, if you calculate how much older the father after three years is than Xiao Ming three years later, it is 39 + 3-(12 + 3) 28 years old.

This year, Xiao Ming is 39 12 27 years older than his father, and 3 years later, Xiao Ming is 15 years old and his father is 42 years old, and his father is still 27 years older than Xiao Ming.

39 12 24 years old, no matter if it is another 3 years or another 50 years, Dad is still 24 years older than Xiao Ming!

A: Three years later, my father is 27 years older than Xiao Ming. Because this year, Dad is 27 years older than Xiao Ming, and the age difference between Dad and Xiao Ming is not.

Three years later, Xiao Ming will be 15 years old, and his father will be 42 years old, and he will be 42 15 27 years old, so three years later, his father will be 27 years older than Xiao Ming.

Three years later, Dad and Xiao Ming are both three years older, so the age difference remains the same, still 27 years old.

27 years old. Xiao Ming is growing up, and so is his father. Calculation method:

27 years older, 39-12 = 27, how much older is this year, and how old will it be three years later.

First of all, if you mean Xiao Ming's father when you say "I", then ten years ago, my father was 25 years older than Xiao Ming. The age difference between parents and children is fixed, Xiao Ming was 13 years old last year, then he is 14 years old this year, and the difference between his 39-year-old father is 25 years, so he was 25 years old ten years ago.

Secondly, if the "I" you are talking about is not Xiao Ming's father, then it is unknown.

Dad is 39 years old this year, Xiao Ming was 13 years old last year, this year is 13 + 1 = 14 years old, Dad is 39-14 = 25 years older than Xiao Ming, and 10 years ago he was 25 years older.

10 years ago, my father was 25 years older than Xiao Ming.

Dad is 37 years old.

Analysis: 5 years later, Xiao Ming is 12 years old, that is, 7 years old this year, and his father is 30 years old, so his father is 37 years old this year.

5 years later, Xiao Ming is 12 years old, then he is 7 years old this year, Xiao Ming and his father are 30 years old, and his father is 37 years old this year.

37 years old. 12 minus 5 is equal to 7 years old, 30 plus 7 is equal to 37 years old, the difference between Xiao Ming and Dad is 30 years old, 5 years later, Xiao Ming is 12 years old, then Dad is 37 years old this year. The theory is respectful of:

To know how much more one number is than another, find another number, and use subtraction. If you know how much more one number is than another, find this number and add it.

31-7 = 24 (years), no matter how many years later, Xiao Ming's father is 24 years older than Xiao Ming.

This question belongs to a brain teaser, no matter how young he is, his father is always 31-7=24 years older than Xiao Ming.

Xiao Ming is 13 years old, and his father is 48 years old, so it is calculated that he is 35 years older than Xiao Ming, 48-13 = 35 (years old). When Xiao Ming was a few years old, his father's age was 35 plus how old Xiao Ming was to get his father's age.

Solution: After 15 years of closure, Dad's age is 36 + 15 = 51 (years old), and Xiao Ming's age is 9 + 15 = 24 (years old). So after 15 years, Dad's age is equal to 51-24=27 (years) when Dad's age is older than Xiao Ming.

36-9 = 25 years old.

Dad is 25 years older than Xiao Ming.

The age difference between Dad and Xiao Ming has always remained the same, at 28 years old.

Daddy's age Ming's age is 3

Dad's age - Ming's age is 28

28 (3-1) 14 years old.

14-7 7 years old.

28+7 35 years old.

A: Xiao Ming is 7 years old this year, and my father is 35 years old.

In another 10 years, Dad's age will be 32+10=42. Our age is equal to 8 + 10 = 18. So Dad is 42-18=24 years older than Xiao Ming.

Because Dad's age is the same as Xiao Ming's age, their age difference is also the same.
