Answer:
9 times
Step-by-step explanation:
Area = length x breadth
area of picture not enlarged = 3 x 5 = 15in²
If length is tripled it becomes , 3 x 3 = 9in
If width is tripled, it becomes , 5 x 3 = 15in
Area of enlarged picture = 9in x 15in = 135in²
amount by which enlarged image is larger = 135in² /15in² = 9
5/12 and 3/8 is the answer
I think I would set a proportion for this. 1 1/2 hours is 90 minutes. So 90 minutes and 90 miles.
90 300
—- = ——.
90 X
As you can see, miles on top and minutes on the bottom. Now, cross multiply. 90x = 300(90)
90x=27,000
Divide by 90 on both sides to get x alone.
90x/90= x 27,000/90=300
300 minutes would be 5 hours!

For this case we must compare the unit costs of the options given and determine which is the best option.
Option 1:
Six yards of rope costs $5.50
Option 2:
Four yards costs $ 4.75
Thus, the best option is the first. It is the lowest unit cost.
Answer:
The best option is the first. It is the lowest unit cost.
