Dear SajjadAhmad,

I'm happy to respond. :-)

Not very challenging--basically, this question is asking whether we know how to divide decimals.

\(b = \frac{0.35}{0.20}a = \frac{3.5}{2}a = 1.75a\)

OA = (D)

Does all this make sense?
Mike :-)

0.35a = 0.2b
or b = 0.35a/0.2 = 1.75a

Option D

We are given that 0.35a = 0.2b. To isolate b, we can multiply both sides by 5.

5(0.35a) = 5(0.2b)

1.75a = b

Answer: D

(D) 1.75a
(E) 17.5a


Given: 0.35a = 0.2b
Multiply both sides by 10 to get : 3.5a = 2b
Divide both sides by 2 to get : 1.75a = b

Answer: D

Cheers,
Brent
