2.IF an american dollor is worth about 3/2 of a Canadian dollor, about how many Canadian dollars will she get for $50?
3. Rosa's grandmother bought her a $100 bond for her tenth b-day. On her 11th b-day, it was worth $106. By what fraction did the bond's value increase? If this pattern continues, how much would the bond be worth on Rosa's 12th b-day?
Thank you SO MUCH!

Answer 1

1) 550/77000
divide both by 550
=1/140

2)x/50=3/2
cross multiply
150=2x
x=75

3)6/100 increase
3/50 increase
106+106*.06= $112.36

Answer 2

1. Vic owns 550/77000 of the company = 55/7700 (divide by 11) = 5/700 (divide by 5)= 1/140

2. US$2 = CN$2
so US$50 = 50/(2/3) = 50*(3/2) = CN$75

3. The bond increased by 6/100 or 3/50. Provided this pattern continues, it will be worth $112.

Answer 3

1. What you have to do is make a fraction. VIc owns 550/77000 shares. This reduces to 55/ 7700 which further reduces to 1/140.

2. 1 american dollar is worth 3/2 of a Canadian dollar. Multiply $50 by 3/2 which gives you $75.

3. I don'tknow.

Answer 4

hey sweetie take the nuber 550 and put it over 77000 and take out the zeros
55/7700 divide it by 5
5 into 55 is 11
5 into 7700 is 1540
11/1540
will 11 go into 1540?

yes
did it help?

Answer 5

1. 550/77000... simplifies to 55/7700
2.50X (3/2) =75Canadian Dollars
3.6%, second part depends on whether the interest is compounded or not

Answer 6

1. 550 shares over 77000 alltogether equals a fraction of 550/ 77000
2. 50 times 3/2 = 75 candaian dollars
3. I DUNNO
