Question

please give me the answer ​

Answer 1

Given :-

• ɴᴜᴍʙᴇʀ ᴏғ ʙᴏʏs ɪɴ ᴄʟᴀss = 20
• ɴᴜᴍʙᴇʀ ᴏғ ɢɪʀʟs ɪɴ ᴄʟᴀss = 20

To Find :-

• ᴡʜᴀᴛ ɪs ᴛʜᴇ ʀᴀᴛɪᴏ ᴏғ ɢɪʀʟs ᴛᴏ ᴛʜᴇ ᴛᴏᴛᴀʟ ɴᴜᴍʙᴇʀ ᴏғ sᴛᴜᴅᴇɴᴛs ᴏғ ᴛʜᴇ ᴄʟᴀss

Required Answer :-

• ғɪʀsᴛ ᴏғ ᴀʟʟ ᴡᴇ ғɪɴᴅ ɴᴜᴍʙᴇʀ ᴏғ ᴛᴏᴛᴀʟ sᴛᴜᴅᴇɴᴛs ɪɴ ᴄʟᴀss
• = 20 ʙᴏʏs + 20 ɢɪʀʟs
• = 40 sᴛᴜᴅᴇɴᴛs

• ɴᴏᴡ ғᴏʀ ᴛʜᴇ ʀᴀᴛɪᴏ ᴏғ ɢɪʀʟs ᴛᴏ ᴛʜᴇ ᴛᴏᴛᴀʟ ɴᴜᴍʙᴇʀ ᴏғ sᴛᴜᴅᴇɴᴛs ᴏғ ᴛʜᴇ ᴄʟᴀss.
• = ɴᴜᴍʙᴇʀ ᴏғ ɢɪʀʟs : ɴᴜᴍʙᴇʀ ᴏғ ᴛᴏᴛᴀʟ sᴛᴜᴅᴇɴᴛs
• sᴏ,

$➝ \: \: = 20 : 40 \\ \\ ➝ \: \: = \frac{20}{40} \: \: \: \: \: \: \: \: \\ \\ ➝ \: \: = \frac{2}{4} \: \: \: \: \: \: \: \: \: \: \\ \\ ➝ \: \: = \frac{1}{2} \: \: \: \: \: \: \: \: \: \: \\ \\ \: \: ➝ \: \: \pink{ʜᴇɴᴄᴇ} \: \: \: \: \: \: \: \\ \\ ➝ \: \: 1 : 2 \: \: \: \: \: \: \: \: \: \: \:$
