Answer 1

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!

Answer 2

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
