Giải:

         \(\dfrac{9}{A}\) = \(\dfrac{B}{8}\) = \(\dfrac{15}{20}\) = \(\dfrac{C}{24}\)

          \(\dfrac{9}{A}\) = \(\dfrac{15}{20}\) = \(\dfrac{3}{4}\)

           A = 9 : \(\dfrac{3}{4}\) = 9 x \(\dfrac{4}{3}\) = 12

          \(\dfrac{B}{8}\) = \(\dfrac{15}{20}\) = \(\dfrac{3}{4}\)

          B = \(\dfrac{3}{4}\) x 8 = 6

          \(\dfrac{C}{24}\)  = \(\dfrac{15}{20}\) = \(\dfrac{3}{4}\)

          C = \(\dfrac{3}{4}\) x 24 = 18

Vậy A + B - C = 12 + 6 - 18 = 0

Chọn b.0
