Question

What fraction should be added to 1 by 4 or 1/4 to get the fraction equivalent to 0.6?
(A) 11/20
(B) 1/3
(C) 7/20
(D) 1/10​

Answer 1

Answer:

c) 7/20

Step-by-step explanation:

let fraction added be x

1/4 + x = 0.6

(we can write 0.6 as 6/10 = 3/5)

x = 3/5 - 1/4

(LCM = 20)

x = 3×4/20 - 1×5/20

x = 12/20 - 5/20

x = 7/20
