Answer 2

Answer:

converting into decimal

Step-by-step explanation:

7 cm and 5 mm is to be converted into cm using decimals.

We know that, 1 cm = 10 mm.

Now converting the given length in mm (millimeters) first and then converting into cm (centimeters).

Now 7 cm 5 mm = 7×10 + 5 = 70 + 5 = 75 mm.

Now converting into cm = 75/10 cm= 7.5 cm.
