Question
Kim’s mother wants to make 3 ribbons of equal length. She has 21 inches of ribbon. Find each ribbon’s length.
- 12 inches
- 3 inches
- 7 inches
- 5 inches
Hint:
Division in maths is the process of breaking a number up into equal parts, and finding out how many equal parts can be made.
The correct answer is: 7 inches
Here, we have to find each ribbon's length.
Ribbon's length = 21 inches
Number of ribbons, kim's mother want to make = 3
We simply divide 21 by 3 .
21 ÷ 3 = 7
Therefore, each ribbon length = 7 inches.
Hence, the correct option is (c).
We know that division is the repetitive subtraction. We have to subtract 3 from 21 till we get 0. So, we need to subtract it for 7 times.
