Answer:
7/25
Step-by-step explanation:
Original contents of the box:
18 green marbles
8 white marbles
Contents of the box after drawing 1 white marble:
18 green marbles
7 white marbles
Total: 25 marbles
p(white) = (number of white marbles)/(total number of marbles)
p(white) = 7/25
Answer:
£714.00
Step-by-step explanation:
The first step is to set up expresssions for the two shares:
Let x = the amount of one share. The other share is 1785 - x. <u>You don't have to worry about which is smaller--that part will work out automatically</u>!
The two shares are in the ratio of 2:3, so set up the proportion
Again, you don't have to worry--you could set up the proportion "upside down" and everything will work out in the end.
Solve the proportion for x by "cross multiplying" -- use the Means-Extremes Property of proportions.
So one share is £714£ and the other is £1785 - £714 = £1071.
The smaller share is £714.
