The answer is:
10.8 cm
Step-by-step explanation:
6 × 1.8 = 10.8
- firstly, remove the decimal point
- Secondly, multiply regularly 6 by 18
- You'll get 108 as an answer
- Take back the decimal point one to the left because you took it one to the right before, so you will have to do the inverse of the previous action
Good luck
