The ratio of {} is {} after 1.6:0.24 reduction

The ratio of {} is {} after 1.6:0.24 reduction

The ratio of {20:3} is {20 / 3}

Find the rule: 1 / 4, 2 / 9, 6 / 16, 34 / 25, 120 / 36 () () 1 / 2, 1 / 3, 1 / 6, 1 / 18
() () random detour

1 / 4, 2 / 9, 6 / 16, 34 / 25, 120 / 36 () 34 / 25 should be 242 / 25, 1 / 3, 2x1, 2x3, 6x4. So in brackets, it is "7 / 7, 120x6, 1 / 6 = (2x3

Calculation: (- 81) △ 2 and 1 / 4 - (- 4 / 9) × 27 / 16 = []

=-81÷(9/4)+(4/9)×27/16
=-81×4/9+3/4
=-36+3/4
=-35 and 3 / 4

Math problem: (- 81) △ 9 / 4 * 4 / 9 * (- 16)! Disjunction calculation @! Kneel down!

xuduode,
（－81）÷9/4×4/9×（－16）
＝－81×4/9×4/9×（－16）
＝1×4/1×4/1×16
＝256
