1 cm = 10 mm

1) Using proportion:

1 cm 10 mm

x cm  3 mm

x = 1 cm * 3 mm/10 mm = 0.3 cm

2) 3 mm * 1cm/10mm = 0.3 cm

3mm = 0.3 cm

Step-by-step explanation:

1 cm = 10 mm

3mm = 3/10 = 0.3cm

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
