jika a=25,b=8,dan c =12, maka 4a:(2b:2c)x1 1/2=

4(25):(2(8):2(12)).3/2 =
100:(16:24)3/2
100:(16/24)3/2
100: (4/6)(3/2)
100:1
=100

a=25
b=8
c=12

4a ÷ (2b÷2c)×1½
4(25)÷(2(8)÷(2(12))×1½
100÷(16÷24)×1 ½
[tex] \frac{100}{ \frac{16}{24} } \times 1 \frac{1}{2} \\ 100 \times \frac{24}{16} \times \frac{3}{2} \\ 100 \times \frac{3}{2} \times \frac{3}{2} \\ 100 \times \frac{9}{4} \\ 25 \times 9 = 225[/tex]
