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

$\large \tt 6\frac{13}{15} + 1 \frac{4}{5}$

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.

• $\large \tt \frac{13}{15} + \frac{4}{5} = \frac{ \: }{15} + \frac{ \: }{15}$

- 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.

• $\large \tt \frac{1 \times 13}{15} + \frac{3 \times 4}{15} = \frac{13}{15} + \frac{12}{15}$

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

• $\large\tt \frac{13}{15} + \frac{12}{15} = \frac{25}{15}$

- Simplify

• $\large \tt \frac{25}{15} = 1 \frac{2}{3}$

- Then, combine the whole and fraction parts

• $\large \tt 6 + 1 + 1 \frac{2}{3} = 8 \frac{2}{3}$

Therefore, $\large\tt 6\frac{13}{15}$ plus $\large\tt 1\frac{4}{5}$ is $\large\tt 8\frac{2}{3}$

Answer:

hello

Step-by-step explanation:

6 3/15 is 93/15 and 14/5

93/15 + 14/5= 93/15 + 42/15= 135/15

135/15 is equal to 9
