SOLVING WORD PROBLEMS INVOLVING SUBTRACTION
Question 1 :
I have 35 jelly beans. Then i eat 12. How many are left ?
Solution :
Number of jelly beans i have = 35
Number of jelly beans i eat = 12
Number of jelly beans left = 35-12
= 13
Question 2 :
Two numbers add up to 30. One of the number is 18. What is the other number ?
Solution :
Sum of two numbers = 30
One of the number = 18
The other number = 30 - 18
= 12
So, the other number is 12.
Question 3 :
A piece of wood of 60 inches long. A section 28 inches long is cut off. How long is the remaining piece of wood ?
Solution :
Length of wood = 60 inches
Length of wood cut off = 28
Remaining piece of wood = 60 - 28
= 32
So, length of remaining piece of wood is 32 inches.
Question 4 :
Rebecca read 213 pages of a book on Saturday. On Sunday she read some more pages of the book. If Rebecca read 416 pages in all, how many pages did she read on Sunday ?
Solution :
Number of pages she read on Saturday = 213
Number of pages she read in all = 416
213 + Number of pages she read in Sunday = 416
Number of pages she read in Sunday = 416 - 213
= 203
Number of pages she read on Sunday is 203.
Question 5 :
Steve drove 158 miles on Saturday. On Sunday he drove 223 miles. How many miles did he drive in all on Saturday and Sunday.
Solution :
Number of miles he drove on Saturday = 158 miles
Number of miles he drove on Sunday = 223
Total number of miles he drive in Saturday and Sunday
= 158 + 223
= 381
Question 6 :
Kevin subtracts 149 from 256. He says the difference is 113. Is he correct?
Solution :
256 - 149 = 107
The difference is 107, but he says the difference is 113.
So, he is incorrect.
Question 7 :
The museum displays some butterflies in Room A and 203 butterflies in Room B. If the meseum displays 445 butterflies in all, how many does it display in Room A ?
Solution :
Number of butterflies in room A + room B = 445
Number of butterflies in room A + 203 = 445
= 445-203
= 242
So, the number of butterflies in room A is 242.
