Looks like an incomplete question.
Can u pls post the choices.

thanks

its purely calculative

May be I can give you some tricks for fast calculations:

we have m+w+c=1

9/25 +15/32 +c =1

663/800 + c = 1 [solving by taking LCM]

c = 1- 663/800

c= 137/800

When we have to compare numbers with different denominators(Dr'), we make there Drs' equal just for sake of comparison


so m = 9/25
Multiply by 4 both numerator (Nr') and Dr'
m = 36/100

Further multiply by 8 both Nr' and Dr' as we have the max Dr' as 800

m= 288/800

Similarly w = 15/32
Multiply Nr' and Dr' By 25

w =375/800

c= 137/800


So C> M > W

Here the answer should be:

C < M < W

greater the numerator => greater the fraction.

w is just less than 16/32 = 1/2 = 0.5, while m is 0.36. Since m+w+c = 1, c must be very close to zero (using our estimate of w, c is close to 0.14 in value), and c < m < w.

Awesome
No calculation is required at all.
just pure common sense.
Stewart you ROCK.
