It is 1275.
You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
3 and 2/5 is equal to 17/5. Multiply 3 x 5/5 to get 15/5, then add the other 2/5 = 17/5
Divide the integer part by the denominator, and add the numerator. Put the result over the denominator. Example: 5 2/3 (five and two-thirds): multiply 5 x 3, add 2. Result is 17. Now put 17 over the original denominator, and you get 17/3.
5 and 17
The prime factorization of 255 is 3 x 5 x 17.
1 x 255, 3 x 85, 5 x 51, 15 x 17, 17 x 15, 51 x 5, 85 x 3, 255 x 1
24 ; 72; 18; 23; 17.
For example, 5 2/3 = 17/3. To obtain this result: Multiply the integer (5 in this case) by the denominator (3), and add the numerator (in this case, 5 x 3 + 2 = 17). Write this numerator over the same denominator used in the mixed fraction.
For example, 5 2/3 = 17/3. The way to get this is to multiply the integer part (in the example, 5) by the denominator (3) and add the numerator (2). In this case, 5 x 3 + 2 = 17. This number is placed as the numerator; the denominator is the same as in the original fraction.
Since 5, 17, and 14 have no common factors, simply multiply the numbers together: 5*17*14=1190
For example, to convert 5 2/3 to an improper fraction, you multiply 5 x 3, then add 2. The result - 17 in this case - is written over the denominator, to get 17/3. So, the general rule is to multiply the integer by the denominator, and add the numerator. This will be the numerator of the result. The denominator doesn't change.
