Question

Please solve the following proportion, and I will award brainiest to first correct answer.

Answer 1

Answer:

x=5

Step-by-step explanation:

2 2/7 : (0.6x) :: 4/21 : 0.25

Hence, as it is in a perfect proportion, we may use the proportion method..

We multiply the extreme terms and the moderate(near) ones and equalise them.

Hence,

(2 2/7)×(0.25) = (0.6x × 4/21)

16/7 × 25/100 = 6x/10 × 4/21

16/7× 1/4= 3x/5 × 4/21

(16/7 × 1/4)/(4/21) =3x/5

16/7×1/4×21/4×5/3=x

1/7×21×5/3=x

x=5
