Estimate the sum or difference of the mixed numbers in these activities. 6 13/15 + 1 4/5=


\large \tt 6(13)/(15) + 1 (4)/(5)

Let's solve the fraction part first.

- First let's find the LCD or the number that can be divided by 15 and 5. So, the LCD of 15 and 5 is 15.


  • \large \tt (13)/(15) + (4)/(5) = ( \: )/(15) + ( \: )/(15)

- Second, let's divide the LCD (15) by the denominator of the first fraction (15) and then let's multiply the numerator of the first fraction (13) so, 15 divide by 15 is 1 times 13 is 13, the same goes for the other 15 divide by 5 is 3 times 4 is 12.


  • \large \tt (1 * 13)/(15) + (3 * 4)/(15) = (13)/(15) + (12)/(15)

- Last let's add them, 13 plus 12 is 25 then copy the denominator.


  • \large\tt (13)/(15) + (12)/(15) = (25)/(15)

- Simplify


  • \large \tt (25)/(15) = 1 (2)/(3)

- Then, combine the whole and fraction parts


  • \large \tt 6 + 1 + 1 (2)/(3) = 8 (2)/(3)

Therefore,
\large\tt 6(13)/(15) plus
\large\tt 1(4)/(5) is
\large\tt 8(2)/(3)
