Step-by-step explanation:
Sorry if I'm wrong!
All you need to know is what irrational means and then you can decide is the width is a fraction a whole number or a decimal etc
Here is one example of when you would use the friendly number strategy to subtract.
42 - 18
We will turn the 18 into a friendly number, which is going to be 20.
(42 + 2) - (18 + 3)
44 - 20
Now it is easier to subtract 44 - 20 than it is 42 -18. With 42 - 18 we would have to barrow whereas with 44 -20 we do not have to barrow and we can do it in our head easier and makes it faster.
Answer:
8 cm
Step-by-step explanation:
Megan's scale of drawing : car is 3cm : 2m
or
3 cm drawing ---> 2m actual length
1 cm drawing ---> (2/3) m actual length
Given Megan's drawing is 6 cm, hence,
6 cm drawing ----> (2/3) x 6 m = 4 m
Hence the actual car is 4 m long
Ivan's scale of drawing:car is 2cm : 1m
or
1 m actual length ---> 2 cm drawing
we know from above that the actual car is 4m long, so
4m actual length ---> 2cm x 4 = 8 cm drawing length.
