Let's tackle each number problem one by one:
Find the number that is greater than 3786 by 1231.6.
To find this number, you simply add 1231.6 to 3786:
3786 + 1231.6 = 5017.6
So, the number greater than 3786 by 1231.6 is 5017.6.
Find the number that is smaller than 897 by 234.7.
To find this number, you subtract 234.7 from 897:
897 − 234.7 = 662.3
Therefore, the number smaller than 897 by 234.7 is 662.3.
If 3452 is subtracted from a number, the difference is 1325. What is the number?
Let the unknown number be x . According to the problem, when 3452 is subtracted from x , the difference is 1325:
x − 3452 = 1325
To find x , add 3452 to 1325:
x = 1325 + 3452 = 4777
So, the number is 4777.
By how much does 1365 exceed 485?
To find out how much 1365 exceeds 485, subtract 485 from 1365:
1365 − 485 = 880
Therefore, 1365 exceeds 485 by 880.
The population of a village is 4295. There are 1975 men and 1799 women there. What is the number of children in the village?
To find the number of children, subtract the number of men and women from the total population:
First, add the number of men and women:
1975 + 1799 = 3774
Then subtract this sum from the total population:
4295 − 3774 = 521
So, there are 521 children in the village.
