How to break down 4/5 + 13/15 = 1 2/3
nalin [4]

Answer:

Step-by-step explanation:

The left hand side of the equation contains proper fractions while the right hand side of the equation contains mixed fraction. The mixed fraction can be changed to improper fraction. 1 2/3 becomes 5/3

To breakdown the left hand side of the equation, we would take lowest common factor of 5 and 15. It is 15

Considering 4/5, if 15 divides 5,the result is 3. Multiplying 3 by 4 gives 12. So it becomes

12/15

Considering 13/15, if 15 divides 15,the result is 1, Multiplying 1 by 13 gives 13. So it becomes

13/15

The equation becomes

(12 + 13)/15 = 5/3

25/15 = 5/3

Simplifying 25/15 to its lowest terms, it becomes 5/3 so

5/3 = 5/3

Help help<br><br> Order these fractions from least to greatest.
Dmitrij [34]

Answer:

\frac{5}{9}, \frac{7}{9}, \frac{8}{9}

Step-by-step explanation:

The answer is: \frac{5}{9}, \frac{7}{9}, \frac{8}{9}

And this question isn't to difficult, and the trick is realizing they all have the same denominator.

The denominator is essentially saying how many pieces of the whole (1) is being broken into.

So the denominator 9, means that you're breaking up the number 1 into 9 pieces.

The numerator is telling us how many pieces of this "broken up 1" the number has.

So 8/9 has more of these "broken up pieces" than 7/9, and it's so vitally important that these numbers have the same denominator.

For example: 1/2 and 30/90

30/90 may appear to be bigger, since the numerator of 30, but it's actually smaller.

The reason for this is because we can simplify it to: 1/3 by dividing both sides by 30 so the value remains the same.

Now we can actually compare 1/2 and 1/3 without changing the denominators.

1/3 is "one piece" of a broken up one, that was "broken" into 3 pieces.

1/2 is "one piece" of a broken up one, that was "broken" into 2 pieces.

So if I split one whole, into three pieces, each individual piece is going to be smaller than had I split that one whole into 2 pieces.

So 1/2 is actually bigger than 1/3
