ᴛʜᴇ ǫᴜᴇsᴛɪᴏɴ ɪs ɢɪᴠᴇɴ ɪɴ ᴍɪxᴇᴅ ғʀᴀᴄᴛɪᴏɴ.

ғɪʀsᴛ ᴡᴇ ʜᴀᴠᴇ ᴛᴏ ᴄᴏɴᴠᴇʀᴛ ɪᴛ ɪɴᴛᴏ ɪᴍᴘʀᴏᴘᴇʀ ғʀᴀᴄᴛɪᴏɴ.

ᴄᴏɴᴠᴇʀsɪᴏɴ ᴏғ ᴀ ᴍɪxᴇᴅ ғʀᴀᴄᴛɪᴏɴ ɪɴ ɪᴍᴘʀᴏᴘᴇʀ ғʀᴀᴄᴛɪᴏɴ :-

2 3/4 = (4 × 2 + 3)/4 = 11/4

4 4/5 = (5 × 4 + 4)/5 = 24/5

6 3/8 = (8 × 6 + 3)/8 = 51/8

ᴀᴛǫ,

11/4 + 24/5 + 51/8

ʟᴄᴍ ᴏғ 4, 5 ᴀɴᴅ 8 = 40

= (11 × 10 + 24 × 8 + 51 × 5)/40

= (110 + 192 + 255)/40

= 557/40
