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
