    Hello!

    I calculated my mean extension value for a spring when mass is loaded onto a spring and measured the extension in cm. I got 2.6cm as the extension.

    But I was asked to calculate it to the nearest mm!
    What is 2.9cm to the nearest mm? Also what is 14.9cm to nearest mm?

    I know this isn't complicated but could someone please help me?

    Thanks,
    Anna.

    As, 0.1 cm = 1 mm, 2.9cm and 14.9cm are 2.9cm and 14.9cm respectively.
    Had it been 14.666666...cm then to the nearest mm it would be 14.7cm.

    multiply your answer in cm by 10 to get your answer in mm. then you can round that to the nearest whole number to get your answer to the nearest mm
