➾ GIVEN:

$ᴡᴇ \: ʜᴀᴠᴇ \: ᴛᴏ \: ꜰɪɴᴅ \: ᴡʜᴀᴛ \: ꜱʜᴏᴜʟᴅ \\ \: ʙᴇ \: ᴀᴅᴅᴇᴅ \: ᴛᴏ \: 7 \frac{4}{15} \: ᴛᴏ \: ɢᴇᴛ \: 8 \frac{2}{5}$

➾ TO FIND:

$ᴡʜᴀᴛ \: sʜᴏᴜʟᴅ \: ʙᴇ \: ᴀᴅᴅᴇᴅ \: ᴛᴏ \: \\ 7\frac{4}{15} \: ᴛᴏ \: ɢᴇᴛ \: 8 \frac{2}{5} \: ?$

➾ SOLUTION:

Let "x" be the number that should be added

Then according to question,

$7 \frac{4}{15} + x = 8 \frac{2}{5}$

$\frac{109}{15} + x = \frac{42}{5}$

$x = \frac{42}{5} - \frac{109}{15}$

$x = \frac{126 - 109}{15}$

$x = \frac{17}{15}$

$x = 1 \frac{2}{15}$

$Thus \: 1 \frac{2}{15} \: should \: be \: added \: to \\ 7 \frac{4}{15} \: to \: get \: 8 \frac{2}{5}$
