Does anybody know how to write 45/70 in simplest form????
Answers
To reduce a fraction to a simpler form, find a common factor of the numerator and denominator, and divide them both by it. If they have no common factor, then the fraction is in its simplest form.
Just looking at 45 and 70, we know immediately that they're both multiples of 5 . So let's divide top and bottom by 5 :
45/70 = 9/14 .
That's simpler.
Now, do 9 and 14 have any common factors ? No ? Good. That means that 9/14 is the simplest form of 45/70.
You didn't have to know what it is. You just had to know how to find it.

on average a baby uses 3 times the number of large diapers as small diapers and double the number of medium diapers as small diapers. If the average baby uses 2940 diapers size large and small, how many of each size would be used
Answers
Okay, if I read this correctly, then the number of large diapers is three times as many as small, and the medium diapers are two times as many as small. To set this equation up, assign x as the unknown value. Small = x Medium = 2x and Large = 3x . Add all of these together and equal them to 2940. From here, solve the equation (6x=2940) by dividing the entire thing by 6. You will have x = 490. To find the number of each size, plug it back into the original. Large: 3x = 3(490) = 1470 Medium: 2x = 2(490) = 980 Small: x = 490 Hopefully I read the problem correctly.
50-20 = 3030-15 = 15 15-9 = 6 6-6 = 0 If you were to check your work, you would get 51. What did I do wrong???
Answers
You did everything correctly! I did it myself...all of your subtraction is correct, then I added the answers together and I got 51. Where you trying to get another answer?
You should sum the answers and see: 30 + 15 + 6 = 30 + 10 + 5 + 6 = 40 + 5 + 5 + 1 = 50 + 1 = 51.
