Answer:
3/14 in decimal is 0.21428571428571
3/14 percent is 21.4

alright so you need to find the unit rate for both of these bought items.
5.25(5 1/4) pounds is equal to $2.10 if you set it into an equation
5.25x = $2.10
x represents how much is the price for one pound of banana
to find x you divide $2.10 by 5.25
you can either plug that into a calculator (.4 is the answer)
to divide a fraction
2.10 / 1 ÷ 21/4
switch the 21/4
2.10/1 ÷ 4/21
instead of using division to solve this you actually multiply!(don't ask me why)
2.10 × 4 = 8.4
21 × 1 = 21
now divide 8.4 by 21 = $0.4 for each pound of bananas
do the same on the other persons payment
3.25x = 6.5
x = 0.5
now you answer it. which one is cheaper?
Answer:
there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.
the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%
the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%
the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%
Answer:
3,200 miles
Step-by-step explanation:
To find the amount, we can first find the unit rate, or how many miles it travels in 1 hour. We can do this by dividing 2,200 by 5. We get a total of 40.
Finally, we can multiply 40 by 8 to get a total of 3,200 miles.
