Hi, First of all I'd like to ask you to ask politely next time, and you'll be much more likely to get an answer
here you need the ratio between the length and width of the football field.
For instance, if i had a cake that was 1 meter wide, and a cake that was 2 meters wide, the ratio of width of the first cake to the second cake would be
Which is
Now extending this to your example, you need to form a ratio of the length of the field to the width of the field.
So this is
so putting in the numbers you have given me the ratio is
Now you need to put this into lowest common terms. This means that you need to find numbers that both the top and bottom are divisible by (with no remainder).
To start off, you can see that they are both divisible by 10, because they both have a 0 on the end. So now I will leave it to you to divide both the top and bottom by 10.
Then after this, you will have to identify the next number that both the terms are divisible by. An easy way to do this is to check if they are divisible by any of the prime numbers (2, 3, 5, 7, etc.). Once you find a number that they are both divisible by, you divide them both by that number to get lower terms. You can continue this until you cannot find any number that both top and bottom are divisible by.
Let me know what you get and I will be happy to check the answer for you.
