Answer 1

hello

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

hope it helped

have a nice day

Fractions

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)`
