tlg bantu dr nomor 5-8 pakai cara

5. a. 36,4 / 20 = x / 14
         20 x = 36,4 x 14
         20 x = 509,6
            x = 509,6 / 20
            x = 25,48 cm

   b. 36,4 / 20 = 24 / y
        36,4 y = 20 x 24
        36,4 y = 480
              y = 480 / 36,4
              y = 13,19 cm

6. 2,45 / 1,72 = 21,4 / t
    2,45 t = 21,4 x 1,72
    2,45 t = 36,808
           t = 36,808 / 2,45
           t = 15,02 m

7. 9,5 / 17 = 1,66 / a
     9,5 a = 17 x 1,66
     9,5 a = 28,22
           a = 28,22 / 9,5
           a = 2,97 m

8. a. 160/240 = 8 / w
         160 w = 240 x 8
         160 w = 1.920
                w = 1.920 / 160
                w = 12 cm

   b. 160/240 = h / 15
        240 h = 160 x 15
        240 h = 2.400
               h = 2.400 / 240
               h = 10 cm
