Question

convert them in pq form: .a. 0.675 (bar on 675) b. 0.32 (bar on 2) c. 0.123 (bar on 3) d. 0.00352 (bar on 52)

Answer 1

a) let 0.675(bar on 675) = x

x= 0.675675675----------(1)

1000x = 675.675675675-------(2)

(2-1)

1000x-x = 675.675675--------- minus 0.675675------

999x = 675

x = 675/999

= 225/333

b) 0.32 ( bar on 2) = y

y= 0.3222222----------(1)

10y = 3.2222222--------(2)

(2-1)

10y-y=3.2222222---------minius 0.32222222--------

9y = 3.1

y= 32/90

c) 0.123(bar on 3) = z

z= 0.12333333-------------(1)

100z = 12.333333----------(2)

(2-1)

99z = 12.21

z= 1221/9900

z= 111/900

d) 0.00352(bar on 52) = k

k = 0.003525252-------(1)

1000k = 3.5252-------(2)

(2-1)

999k = 2.997

k= 2997/999000

= 3/1000
