Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

32/y = 24/(24+21)

32/y = 24/45

32/y = 8/15

8y = 32 x 15

8y = 480

y = 480/8

y = 60

x/28 = 24/(24+21)

x/28 = 24/45

x/28 = 8/15

15x = 28 (8)

15x = 224

x = 224/15

x = 14 14/15

x/y = (224/15) / 60

x/y = 224/(15 × 60)

x/y = 224/900

x/y = 56/225
