Nope, 5r + r3s is not a monomial.

We know that Amy has 5 yards of boarders and that she will use them to make 4 equal borders.
This means that:
she will divide 5 yards by 4 to know the length of each border

Among the given choices, choices G, H and J show the division of 5 by 4 which is correct representation of the length
On the other hand. choice F shows the division of 4 by 5 which is an incorrect representation of the length.

What is 650/1000 in simplest form

just olya [345]

When you simplify a fraction, remember to perform the same operation on both the numerator and the denominator, and that there may not be a decimal or a fraction as a numerator or denominator.
You could always start by dividing with the largest common factor that you can recall off the top of your head. I'll use 10 as an example.
650/10 = 65. 1000/10 = 100.
You have now simplified the fraction down to 65/100. But wait! You can simplify this fraction down further. I'll use 5 now. 65/5 = 13. 100/5 = 20. You have simplified it down to 13/20. Because you know that 13 is a prime number, you know you have written the fraction in simplest form.
Hope that helped you!
(Hint: Use divisibility rules to help you divide faster.)
