Question

Add 21 1/2 in. 10 9/16 in.

Answer 1

First convert 1/2 into 8/16 then add your fractions. You should get 17/16 then make it a mixed number. 1 & 1/16. Now add 21+10+1 and you should get 32. So your awnser is 32 1/16 in.

Answer 2

The addition is:

`=(513)/(16)\ in.` or
`32(1)/(16)\ in.`

Explanation:

We are asked to add the expression :

`21(1)/(2)\ in.` and
`10(9)/(16)\ in.`

both the numbers are in mixed fraction .

We will first change both the numbers into simple fraction as follows:

`21(1)/(2)=(21* 2+1)/(2)\\\\\\21(1)/(2)=(43)/(2)\ in.`

and

`10(9)/(16)=(10* 16+9)/(16)\\\\10(9)/(16)=(169)/(16)\ in.`

Hence, the addition of the two numbers is calculated as follows:

`(43)/(2)+(169)/(16)\\\\\\=(43* 8+169)/(16)`

( Since, on taking lcm of 2 and 16)

Hence, we get:

`=(513)/(16)\ in.`

which in mixed fraction is:

`32(1)/(16)\ in.`
