Help im about to fail xd

Subtract. 4 1/3 − 8

Answer 1

`\\ \sf\longmapsto 4(1)/(3)-8`

`\\ \sf\longmapsto (3(4)+1)/(3)-8`

`\\ \sf\longmapsto (12+1)/(3)-8`

`\\ \sf\longmapsto (13)/(3)-8`

`\\ \sf\longmapsto (13-24)/(3)`

`\\ \sf\longmapsto (-11)/(3)`

`\\ \sf\longmapsto -3(2)/(3)`

Answer 2

`\dashrightarrow \: { \tt{4 (1)/(3) - 8 }}`

• first express the mixed fraction into an improper fraction:

`\dashrightarrow \: { \tt{ ((3 * 4) + 1)/(3) - 8}} \\ \\ \dashrightarrow \: { \tt{ (13)/(3) - (8)/(1) }}`

• Find the L.C.M of 3 and 1, L.C.M is 3:

`\dashrightarrow \: { \tt{ (13 - (3 * 8))/(3) }} \\ \\ \dashrightarrow \: { \tt{ (13 - 24)/(3) }} \\ \\ \dashrightarrow \: { \tt{ - (11)/(3) }} \\ \\ \dashrightarrow \: { \boxed{ \boxed{ \tt{ \: \: - 3 (2)/(3) }}}}`
