(6,28 + 9 4/5) × 7,24 - 17 3/8 Tolong sama caranya yg jelas

( 6,28 + 9 4/5 ) × 7,24 - 17 3/8
= (6,28 + 49/5) × 7,24 - 139/8
= ( 6,28 + 9,8 ) × 7,24 - 17,37
= 16,08 × 7,24 - 17,37
= 116,41 - 17,37
= 99,04
= 99

( 6,28 + 9 4/5 ) x 7,24 - 17 3/8
= ( 6,28 + 9,8 ) x 7,24 - 17 3/8
= 16,08 x 7,24 - 17,375
= 116,4192 - 17,375
= 99,0442

Maaf ya kalau salah.
