Question

Find the ratio of the following.

(a) 30 minutes to 2.5 hours
(b) 24cm to 5 m
(c) 75 paise to ₹ 3
(d) 1minute to 45 seconds
(e) 25kg to 250gm
(f) 500 m to 2 km​

Answer 1

a. 30 min : 2.5 hr

= 30 min : 150 min

=

$\frac{30}{150}$

=

$\frac{1}{5}$

= 1 : 5

b. 24cm : 5m

= 24cm : 500cm

=

$\frac{24}{500}$

=

$\frac{6}{125}$

= 6 : 125

c. 75p : Rs.3

= 75p : 300p

=

$\frac{75}{300}$

=

$\frac{1}{4}$

= 1 : 4

d. 1 min : 45 sec

= 60 sec : 45 sec

=

$\frac{60}{45}$

=

$\frac{4}{3}$

= 4 : 3

e. 25kg : 250g

= 25000g : 250g

=

$\frac{25000}{250}$

=

$\frac{100}{1}$

= 100 : 1

f. 500m : 2km

= 500m : 2000m

=

$\frac{500}{2000}$

=

$\frac{1}{4}$

= 1 : 4
