$\frac{27}{4}$ , $\frac{9}{4}$ , $1\frac{7}{4}$ .

Step-by-step explanation:

Given : $6\frac{3}{4}$ , $2\frac{1}{4}$ and $1\frac{3}{4}$ .

To find : What is the reciprocal of each mixed number.

Solution : We have given $6\frac{3}{4}$ , $2\frac{1}{4}$ and $1\frac{3}{4}$ .

First we convert the mixed fraction in to improper fraction :

For $6\frac{3}{4}$ = $\frac{27}{4}$

Reciprocal : when the numerator change into denominator and denominator change in to numerator.

So, Reciprocal of $\frac{27}{4}$ is $\frac{4}{27}$ .

For $2\frac{1}{4}$ = $\frac{9}{4}$

Reciprocal of $\frac{9}{4}$ = $\frac{4}{9}$ .

For $1\frac{3}{4}$ = $1\frac{7}{4}$ .

Reciprocal of $1\frac{7}{4}$ is $1\frac{4}{7}$ .

Therefore, $\frac{27}{4}$ , $\frac{9}{4}$ , $1\frac{7}{4}$ .

5/6

Step-by-step explanation:

9/18 + 1/3 <Need the same denominator so find the lowest common multiple.

3 6 9 12 15 18 < multiples of 3

if 3 goes into 18 than it will be our LCM

3 goes into 18 6 times so multiply 1 and 3 by 6 and rewrite the equation

9/18 + 6/18 < just add 9 + 6 and place it over 18

15/18 <this number can be simplified so write out their factors and pick the highest one to divide by one they have in common.

1 3 5 15 <Factors of 15

1 2 3 6 9 18 <Factors of 18

3 is the highest one they both have so divide both 15 and 18 by 3

15/3 is 5 and 18/3 is 6

put the 5 and 6 in their proper places and you have 5/6 or .83333333333...
