1530ft2 divided by 51ft.
Answer:
The ratio between two values A and B is just the quotient between these two values:
ratio = A/B
a) $280 in 7m
Here the ratio is:
$280/7m = $40/m
This also can be read as:
$40 per meter.
b) 105 miles in 2 hours
Here the ratio is:
105mi/2h = 52.5 mi/h
This also can be read as:
52.5 miles per hour
c) $33 for 5lb
The ratio is:
$33/5lb = $6.6/lb
This can be read as:
$6.6 per pound.
d) 50 pages in 2 hours
the ratio is:
(50 pages)/2h = 25 pages/h
this can be read as:
25 pages per hour.
Using a system of equations, it is found that initially Ada has $0.385.
For the system, we have that the variables are:
- x is Ada's amount.
- y is Betty's amount.
- z is Chris's amount.
- w is David's amount.
$45 total, hence:

Ada <u>gets 2 from Betty</u>, hence:



<u>Chris triples</u> his money and <u>David's</u> money is <u>cut by half</u> four of them have the same amount, hence:

Then:




Solving for w, we find Ada's initial amount.







Initially, Ada has $0.385.
