Margo lists the sizes, inches, of set of screws: 9/64, 5/32, 1/16, 1/8. she reasons that because the denominators are in order from greatest to least, the list is in order from least to greatest. is margo correct? why or why not ?

I think she is incorrect she need to change all the fractions to the same denominators

Step-by-step explanation:

We are going to change all the fractions to 64

9/64 stays the same

5/32 multiply 2    then 10/64

1/16 multiply by 4 then 4/64

1/8 multiply by 8  then 8/64

Now we can order then

5/32 > 9/64 > 1/8 > 1/16 This is the right order

She was wrong.

1/8 plus 2/5=you dot know yet so let  me explain to you ok alright 5 can not go into 8 and 8 can not go into 5 so what you need to do is make the denominator 8 times 5 which equals 40. 40 will be both of the denominators then you will do 8 times 2 equal 16 then you will do 5 times 1 which equal5.1/8 is now5/40and2/5 is now 16/40 then you will multiply but when you fro keep the 40 and multiply the numerator .You may have to simplify.
