Answer 1

Answer:

$<font color =goldenpurple>$

First, convert both mixed numbers to improper fractions. You do this by multiplying the base by the denominator, adding the numerator, and making the resulting number the new numerator.

6 1/9 = (6*9+1)/9 = (54+1)/9 = 55/9

2 7/9 = (9*2+7)/9 = (18+7)/9 = 25/9

Therefore, we are left with the following:

55/9 - 25/9

Re-write this equation as a single fraction to simplify the subtraction:

(55–25)/9 = 30/9

Reduce the fraction with a GCF of 3:

30/9 = 10/3

Answer 2

Answer:

${\bold{\green{\underline{ ★ \: UPSC - Aspirant \:★ }}}}$

$\sf{ 6 \:1/9 = 6*9+1)/9 = (54+1)/9 = 55/9}$

$\sf{ 2\:7/9 = (9*2+7)/9 = (18+7)/9 = 25/9}$

$\huge\sf{55/9 - 25/9}$

$\huge\sf{55-25)/9 = 30/9}$

$\huge\sf{Reduce \: the\: fraction\: with \:a \:GCF \:of \:3 :}$

$\huge\sf{ 30/9=10/3}$

$\huge\boxed{ → 10/3}$
