ok, i'm having problems figuring out how to add these fractions, here's an example: 5 7/16-4 1/19-9 3/17 = ? pleeeez help!!!!!

I would change each mixed fraction as follows to a fraction:

5 7/16 = (5*16)+7 = 87/16
4 1/19 = (4*19)+1 = 77/19
9 3/17 = (9*17)+3 = 156/17

Then find the lowest common decnominator and go from there.

that's the problem i'm having now, i can't for the life of me find the common denominators, i have never felt more stupid in my life!!

A suggestion is to go and google how to find a common denominator in fractions

click on the first site on the list and it should help you with the lowest common denominator

hope it helps =D

I meant the 2nd site

When all else fails, you can always use 16*17*19. That may not be the lowest but it will always work. The final answers may be reducible.

i need help with fractions!!!!!!

Sure, I can help you with that!

To add fractions, we need to find a common denominator. In this case, the denominators are 16, 19, and 17. To find the least common multiple (LCM) of these denominators, we can use either prime factorization or a common method like finding the LCM using basic multiplication.

Here's a step-by-step method to add these fractions:

Step 1: Convert the mixed numbers into improper fractions.
- 5 7/16 can be converted to (5 × 16 + 7)/16 = 87/16
- 4 1/19 can be converted to (4 × 19 + 1)/19 = 77/19
- 9 3/17 can be converted to (9 × 17 + 3)/17 = 156/17

Step 2: Find the common denominator.
The common denominator for 16, 19, and 17 can be found using multiplication. In this case, the LCM is 51,424.

Step 3: Rewrite the fractions using the common denominator.
- 87/16 can be rewritten as (87 × 3202)/(16 × 3202) = 278,874/51,424
- 77/19 can be rewritten as (77 × 2692)/(19 × 2692) = 207,484/51,424
- 156/17 can be rewritten as (156 × 3024)/(17 × 3024) = 470,544/51,424

Step 4: Add the fractions together.
Now that we have all three fractions with the same denominator, we can simply add the numerators:
278,874/51,424 + 207,484/51,424 + 470,544/51,424 = (278,874 + 207,484 + 470,544)/51,424

Step 5: Simplify, if needed.
Calculate the numerator: 957,902
The final fraction is 957,902/51,424.

So, 5 7/16 - 4 1/19 - 9 3/17 is equal to 957,902/51,424.

Note: If you prefer working with mixed numbers as the final answer, you can convert the fraction 957,902/51,424 back into a mixed number by dividing the numerator by the denominator and expressing the remainder as a fraction.
