Question

Find the ratio of the following:

(a) 30 minutes to 1.5 hours

(b) 40 cm to 1.5 m

(c) 55 paise to ₹ 1

(d) 500 ml to 2 litres​

Answer 1

$\huge\underline\mathrm{SOLUTION:-}$

(a) 30 minutes to 1.5 hours

30 min = 30/60

= 0.5 hours

Required ratio = (0.5 × 1) / (0.5 × 3)

= 1/3

(b) 40 cm to 1.5 m

1.5 m = 150 cm

Required ratio = 40/150

= 4/15

(c) 55 paise to ₹ 1

₹ 1 = 100 paise

Required ratio = 55 / 100

= (11 × 5) / (20 × 5)

= 11/20

(d) 500 ml to 2 litres

1 litre = 1000 ml

2 litre = 2000 ml

Required ratio = 500 / 2000

= 5 / 20

= 5 / (5 × 4)

= 1/4

Answer 2

Answer:

☆ Question - find the ratio of the following

☆ To find - Ratio

☆ Solution -

i) 30 min to 1.5 hrs

1hr = 60 min

1.5 hr = ?

1.5 × 60 = 90.0 min

30 min to 90 min

30/90

1/3

= 1:3

b) 40 cm to 1.5 m

1m = 100 cm

1.5 m = ?

1.5 × 100

150 cm

40 cm to 150 cm

40/150

4/15

4: 15

c) 55 paise to 1 rs

100 paisr = 1 rs

55 paise to 100 paise

55/100

11/20

11:20

d) 500 ml to 2 l

1000 ml = 1 l

? = 2 l

500 ml to 2000 ml

500/2000

1/4

1:4
