Order of magnitude

Question 1

a pineapple next to a lemon is 10x larger than the lemon

what is the order of magnitude?

Answer 1

The pineapple is 1 order of magnitude larger than the lemon

Question 2

what does 1 order of magnitude mean?

Answer 2

1 order of magnitude means 10x

Question 3

If a dog is 100x larger than the woodlice, this would mean that the dog is …

Answer 3

2 orders of magnitude larger than the woodlice

Question 4

every order of magnitude is __x greater than the one before so

a) 1 order of magnitude =
b) 2 orders of magnitude=
c) 3 orders of magnitude=

Answer 4

every order of magnitude is 10x greater than the one before so
a)1 order of magnitude = 10^1= 10
b)2 orders of magnitude=10^2=100
c)3 orders of magnitude=10^3= 1000
to remember this you can think of one zero is 1 order of magnitude
two zeros means 2 orders of magnitude
three zeros means 3 orders of magnitude

Question 5

one zero is _ order of magnitude
two zeros means _ orders of magnitude
three zeros means _ orders of magnitude

Answer 5

one zero is 1 order of magnitude
two zeros means 2 orders of magnitude
three zeros means 3 orders of magnitude

Question 6

a fox is around 40cm long, a tick living on the fox is around 0.4cm long. How many orders of magnitude is the fox longer than the the tick?

Answer 6

2 orders of magnitude
40cm / 0.4= 100
100x = 2 zeros = 2 orders of magniture
