If the equation can be easily calculated, it can be simply calculated [5 / 8 - (3 / 8 + 1 / 6)] × 8 / 9

If the equation can be easily calculated, it can be simply calculated [5 / 8 - (3 / 8 + 1 / 6)] × 8 / 9

[5 / 8 - (3 / 8 + 1 / 6)] × 8 / 9
=[5 / 8-3 / 8-1 / 6] × 8 / 9
=[1 / 4-1 / 6] × 8 / 9
=1 / 12 × 8 / 9
=2 / 27
