m = $$\frac{9}{25}$$ > which is around $$\frac{1}{3}$$

w = $$\frac{15}{32}$$ > which is around $$\frac{1}{2}$$

Together m & w would constitute around $$\frac{5}{6}$$, so the remaining c would be around $$\frac{1}{6}$$ which is far less than m & w

Increasing order: c, m w

Ans e wmc

w = 15/32 ~0.4
m = 9/24 = 0.36

c = 1 - (w + m) ~ 0.24

so w m c in descending order another everything I do after 1 AM I seem to miss

ascending: c m w..

Answer a - c, m, w

m ~ 1/3
w ~ 1/2

and m+w+c = 1 hence c ~ 1/6

Hence increasing order would be c -> m -> w

If m = 9/25, w = 15/32, and m + w+ c = 1, which of the following gives the values of m, w, c in increasing order?

a.c, m, w
b.c, w, m
c.m,w,c
d.w,c,m
e.w,m,c

w is approx = half

m is approx = 0.4
thus sure

a is the answer increasing order ( c<m<w)

Yes, decimals work faster than common denominators here. E would be correct if the question asked for DESCENDING order.

m = 9/25 = 0.36
w = 15/32 = 0.4
On substituting C = 0.24
c , m , w

If m = 9/25, w = 15/32, and m + w + c = 1, which of the following gives the values of m, w, and c in increasing order?

A. c, m, w
B. c, w, m
C. m, w, c
D. w, c, m
E. w, m, c

One can solve this one using 2 methods.

Method 1
- See the way PAresh did it. I've solved this the same when saw this problem in the test.

Mehod 2
$$\frac{9}{25} = \frac{54}{150}$$ and $$\frac{15}{32} = \frac{75}{150}$$, so $$1-\frac{54}{150}-\frac{75}{150}$$, so it's evident that c<m<w

That made the problem look so easy

Hi,

Since we are going to use a lot of percent to decimal to fraction conversion, best is to convert in to % and compare.

Well lets see how the fractions fair in terms of "%"
so "m"= $$\frac{9}{25}$$ is 36%.
w= $$\frac{15}{32}$$< $$\frac{15}{30}$$

$$\frac{1}{30}$$ is close to 3.33%

$$\frac{15}{32}$$ is 46%

so c =100-(36+46)= 18%

19<36<45
c<m<w
