Question

Are the ratios, 7 m: 900 cm and
42 kg : 54,000 g, in proportion?​

Answer 1

Answer:

7m = 700 cm

42 kg = 42000g

        ∴ 700 : 900 = 42000 : 54000

            7 : 9 = 42 : 54

               $\frac{7}{9} = \frac{42}{54}$

               $\frac{1}{1} = \frac{6}{6}$

               $\frac{1}{1} = \frac{1}{1}$

             1 : 1 = 1 : 1

          Hope it helps you^_^
