Answer:
(a) 3:5
(b) 15
Step-by-step explanation:
Well first we need to create a ratio for the 5 shades squares and 3 non+shaded squares.
It is asking for unshaded first so our ratio will be,
3:5
(a) 3:5
So if there is 9 unshaded how many shaded is there.
Well we can just make the following ratio 9:x
So 9/3 = 3
Meaning 3*5 = 15
So x = 15
(b) 15
Answer:
a) 3/5
b) 15
Step-by-step explanation:
(a)
unshaded: 3
shaded: 5
unshaded to shaded: 3/5
(b)
There are now 3 unshaded squares. You need 9 unshaded squares, so you need to have three times as many total squares as you have now.
Add two more lines just like the given line.
Each new line will have 5 shaded and 3 unshaded squares.
Now you have a total of 9 unshaded and 15 shaded squares.
