Which of the following expression has a value equal to 5?

Answer 1

$\huge \fbox \pink {ᴄᴏʀʀᴇᴄᴛ\:ǫᴜᴇsᴛɪᴏɴ}$ =Which of the following expressions has the value 4/5

1. 1/5 + 3/10

2. 1/5 + 2/3

3. ½ + 3/10

4. 4/15 + 2/15

Now we need to find out of these expressions which results in 4/5.

So 1/5 + 3/10

     2 + 3 / 10

       5/10

      = ½  

So 1/5 + 2/3

  3 + 10 / 15

     = 13/15

So ½ + 3/10

  = 5 + 3 / 10

 = 8/10

= 4/5 so this expression holds good.

So 4/15 + 2/15

     = 4 + 2/15

     = 6/15

     = 2/5
