We have an equation: 2/1= ?/2.25
Cross multiply:
1*?= 2*2.25
⇒ ?= 2*2.25= 4.5
The final answer is 4.5~
Answer:
You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.
Step-by-step explanation:
You have 3 1/4 pizzas. If you get rid of 3/4 of a pizza, you will end up with 2 2/4 pizzas.
To make it easier, you can just change the values into improper fractions: 3 1/4 = 13/4
13/4 - 3/4 = 10/4
10/4 = 2 2/4 pizzas
(2 2/4 = 2 1/2)
Anyways! You now have 2 and a half pizzas. You have 3 times the amount of pizza that your friend has. In other words, your friend has 1/3 the amount of pizza that you have. You can solve for this in two ways, whichever way you solve it is up to you.
- You can solve this problem by dividing the amount of food you have by 3:
which equals 0.8333... (the 3 is repeating). But you can just keep your final answer in fraction form if you want to: 
- You can solve this problem by multiplying 1/3 to the amount of food you have:

You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.
Answer:
so, 10 laps in 25 mins we want to make mins=1 so
10/25=2/5 times 5/5=2/5
if you multiply 2/5 by 2/2 then you get 4/10 and 4/10=0.4
the runner can run 0.4 or 2/5 lap in 1 minute
Step-by-step explanation:
it is the answer box I'm a genius
2/4? 4/8? .5? All mean 1/2. Also one half.
The answer would be 44.7 not 44.5
