You can set up rations to do this.
So we know that they accept 2:5.
So It would be 180: 450.
Answer:

Step-by-step explanation:






The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.
And we are asked to find the total area of their grazing but in hectares. So, we can write:

Then, for 4500 cows:


We know that, 1 hectares = 10000 m² = 10⁴ m²
Then let the area of the field be x in hectares:


Then, putting them in proportion, We will get:


So, the total area in hectares = <u>1</u><u>8</u><u>9</u><u>0</u><u> </u><u>hectares</u><u>.</u>
And we are done !!

Answer:
6
Step-by-step explanation:
Label them as variables
A, B, and C
Now try and list them
ABC
ACB
BAC
BCA
CAB
CBA
There should be 6
The more mathematical way is using factorials
So you would do 3! which is 3*2*1
This also gives you 6
