Answer 1

{x; y; z; w} i.p {0,(3); 0,5; 0,2; 0,25}

x/1/0,(3) = y/1/0,5 = z/1/0,2 = w/1/0,25 = k

deci x = k/0,(3) = k/1/3 = 3k

y = k/0,5 = k/1/2 = 2k

z = k/0,2 = k/1/5 = 5k

w = k/0,25 = k/1/4 = 4k

stim ca x+y+z+w = 70

3k + 2k + 5k + 4k = 70

14k = 70

k = 5

x = 3x5 = 15

y = 2x5 = 10

z = 5x5 = 25

w = 4x5 = 20
