Answer:
90
Step-by-step explanation:
Write the ratio this way
Pip: Sara: Total
5 : 4 : 9
We multiply each by 10 to get Pip to 50 (5*10 = 50)
5*10: 4*10: 9*10
50 : 40 : 90
$90
Given that the ratio of Pip: Sara is 5:4
This means :
Pip gets 5 parts
Sara gets 4 parts
Together they have 5 + 4 parts = 9 parts
Also given that Pip's 5 parts is equivalent to $50
Hence each 1 part is $50/5 = $10
if 1 part = $10
The total 9 parts = 9 x $10 = $90
500*10^6 L or 5.00*10^8 L.
Capital M shows mega which equal to 10^6.
So, 500 ML = 500*10^6 L
or 5.00*10^8 L.
