✔ 最佳答案
1)her father 's age =2y2)GARY can get
=(4/3+4)x
=4x/7
3)唔明你講咩
4)5/(8+7+5)
=1/4
5)2/5x100%
=2x20%
=40%

下面嗰位第三條都無話length 係8定6cmif length =6cm the ratio of the length to the perimeter= 6 : 2(8 6)=3 :14if length =8 cm the ratio of the length to the perimeter= 8 : 2(6 8)=2 : 7仲有樓下嗰位第四條要表達成分數而唔係比例

1) 2y
2) 4x/7 = 0.57x
3) perimeter = 2*(8+6) = 28
length : perimeter = 8 : 28
= 2 : 7
4) let sides are 8x, 7x & 5x
perimeter = 20x
shortest side : perimeter = 5x : 20x
= 1 : 4
5) 2/5*100%
= 40%
2) 4x/7 = 0.57x
3) perimeter = 2*(8+6) = 28
length : perimeter = 8 : 28
= 2 : 7
4) let sides are 8x, 7x & 5x
perimeter = 20x
shortest side : perimeter = 5x : 20x
= 1 : 4
5) 2/5*100%
= 40%
