  • 1) We know, 1 mm = 0.1 cm
     So, 85 mm = 0.1 * 85 = 8.5 cm
     Nearest value would be 9 cm

     In short, Your Answer would be 9 cm

    2) 8 pencils = 72 p
    So, 1 pencil = 72 / 8 = 9 p

    In short, Your Answer would be 9 p

    Hope this helps!

  • 1.
    10mm=1cm
    1mm=1/10cm
    85mm=85/10cm
    85mm=8.5cm,
    round to nearest cm
    85mm=9cm


    2.
    8=72p
    divide both sides by 8
    8/8=72p/8
    1=9p
    1 pencil=9p
