Question

find if they are in propostion?
40cm : 2m and 70cm : 3 1/2m

Answer 1

Answer:

if 40/2 = 70/3.5 , then they are in proposition .

40/2 = 20

70/3.5 = 20.

so Both are in proposition.

Answer 2

Answer:

to find weather they are in proportion or not we need to find product of means and product of extreme

Step-by-step explanation:

product of means = product of extreme

2*70              =             40*31/2

140                 =             20*31 (we cancel 40 and 2)

                                               (40/2=20)

2*70=140 =                    20*31=620

they both are not equal so there are not in proportion

have a good day
