Step-by-step explanation:

Answer 2

$8\frac{2}{3}+10\frac{2}{5}$

Step 1: Convert the mixed fraction to improper fraction. To convert a mixed fraction to improper fraction we need to multiply the whole number to the denominator of the fractional part and then add the numerator of the fractional part. After that we get a number which will be the numerator of the improper fraction and the denominator will be the same as in the mixed fraction.

$8\frac{2}{3} = \frac{26}{3}$

$10\frac{2}{5}=\frac{52}{5}$

So now we need to solve this ⇒ $\frac{26}{3} +\frac{52}{5}$

Step 2: Find the LCM of the denominator to make it equal.

LCM of 3 and 5 is 15.

$\frac{26}{3}= \frac{130}{15}$

$\frac{52}{5} =\frac{156}{15}$

Step 3: Add the numerators and let the denominator be the same.

$\frac{130}{15} +\frac{156}{15}=\frac{286}{15}$

Step 4: Convert the fraction to mixed form (this is optional)

$\frac{286}{15}=19\frac{1}{15}$

∴ $8\frac{2}{3}+10\frac{2}{5}=\frac{286}{15}\ or\ 19\frac{1}{15}$
