Length of Ramesh's notebook=9cm5mmWe know 1mm=1/10cmSo,5mm =5/10cmSo, 9cm+ 0.5cm9.5cmAns=It's length will 9.5cm

Length of Ramesh's notebook:

To find the length of Ramesh's notebook, we need to convert the given measurements into a single unit. The length is given as 9 cm 5mm, which means it has a whole number of centimeters and a fraction of millimeters.

Conversion:
1 cm = 10 mm

Step 1:
Convert the given millimeters to centimeters.
5 mm ÷ 10 = 0.5 cm

So, the length of Ramesh's notebook in centimeters is 9 cm + 0.5 cm = 9.5 cm.

Explanation:
Ramesh's notebook has a length of 9 cm 5mm. To convert this measurement into a single unit, we need to convert the millimeters to centimeters. Since there are 10 millimeters in 1 centimeter, we divide the given millimeters by 10 to get the equivalent centimeters.

In this case, we have 5 millimeters, which when divided by 10 equals 0.5 centimeters. Therefore, we add this value to the whole number of centimeters (9 cm) to get the final length of Ramesh's notebook.

Final answer:
The length of Ramesh's notebook is 9.5 cm.
