Theo has a wooden board this is 780 millimeters long. how long is the board, in centimeters? round youre answer to the nearest tenth

78cm

780mm = 780/1000 (m)

therefore 780mm = 0.78 m

but 100cm = 1m

0.78m = 78cm

it should be 78 centimeters

Step-by-step explanation:

1 mm=0.1 cm

780 times 0.1= 78 cm

if you want to round to the nearest tenth then it will be 78 because 78.00 rounded to the tenth is 78.0 because we know that is the number after the place that we need to round is 5 or higher then you round up and if it is below 5 it stays that same.
