Keep the two the same so put 2. then you put the 2 in the faction under the division sign then you put the 5 on the outside. The answer should be 2.4.

2 2/5 = 5/5+5/5+2/5 or 12/5

to change a fraction to a decimal you use a calculator of you change it to a fraction then to a decimal

if you multiply a fraction by its recipricol (the number fliped upside down) the you will get 1 so if you multiply 1/2 by 2/1 then you will get 1

so you multiply 12/5 with 100/x=1200/5x=240

you change the percent to a fraction by moving the decimal place two places to the left or divide it by 100

so 240%=2.4 answer

Step-by-step explanation:

The question in English is

4 carrots are needed to prepare a quarter liter of juice. How many carrots do you need to get half a liter of juice, a liter of juice, 2 liters of juice, 3 liters of juice

Part 1) How many carrots do you need to get half a liter of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 1/2 liter of juice

$\frac{4}{(1/4)}=\frac{x}{(1/2)}\\\\x=4(1/2)/(1/4)\\\\x=8\ carrots$

Part 2) How many carrots do you need to get a liter of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 1 liter of juice

$\frac{4}{(1/4)}=\frac{x}{1}\\\\x=4(1)/(1/4)\\\\x=16\ carrots$

Part 3) How many carrots do you need to get 2 liters of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 2 liters of juice

$\frac{4}{(1/4)}=\frac{x}{2}\\\\x=4(2)/(1/4)\\\\x=32\ carrots$

Part 4) How many carrots do you need to get 3 liters of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 3 liters of juice

$\frac{4}{(1/4)}=\frac{x}{3}\\\\x=4(3)/(1/4)\\\\x=48\ carrots$

Answer:

3,992.34 (I think)
