Solution:- Let,
Tʜᴇ ʀᴀᴛɪᴏɴᴀʟ ɴᴜᴍʙᴇʀ ɪs = x

x ɪs ᴍᴜʟᴛɪᴘʟɪᴇᴅ ʙʏ 5/2 = x.5/2=5x/2

Aᴄᴄᴏʀᴅɪɴɢ ᴛᴏ ᴛʜᴇ ᴘʀᴏʙʟᴇᴍ,


$5x \div 2 + 2 \div 3 = - 7 \div 12$
$5x \div 2 = - 7 \div 12 -2 \div 3$
$5x \div 2 = ( - 7 - 8) \div 12$
$5x \div 2 = - 15 \div 12$
$x = ( - 15 \div 12) \times (2 \div 5)$
$x = - 30 \div 60$
$x = - 1 \div 2$
ᴛʜᴇʀᴇғᴏʀ,

Tʜᴇ ʀᴀᴛɪᴏɴᴀʟ ɴᴜᴍʙᴇʀ =x=-1/2
