Answer 2

Answer: (a) 1.74 = 87/50  (b) 1.4 =  7/5  (c)  -3.8 = -19/5 (d) -8.65 bar =-857/99

Step-by-step explanation:

a) 1.74 = 174/100

= 87/50

b) 1.4 = 14/10

= 7/5

c) -3.8 = -38/10

= -19/5

d) -8.65 bar

Let x be equal to  -8.65 bar

x = -8.65 bar   (i)

Now multiply both sides with 100

100x =  -865.65 bar  (ii)

Now subtract (i) from (ii)

99x = -857

x = -857/99

So -8.65 bar = -857/99
