Question

Determine if the following ratios form a proportion. Also, write the middle terms and extreme terms where the ratios form a proportion.

(a) 10 cm: 1 m and ₹ 10: ₹ 100

(b) 39 litres: 65 litres and 6 bottles: 10 bottles

(c) 2 kg: 50 kg and 25 g: 625 g

(d) 200 mL: 2.5 litre and ₹ 4: Rs 50

Answer 1

Step-by-step explanation:

a) 10 cm : 1 m and ₹10:₹100

1 m=100 cm

extremes=means

10×100=100×10

1000=1000

b)39 litres: 65 litres and 6 bottles: 10 bottles

extremes=means

39×10=65×6

390=390

(c) 2 kg: 50 kg and 25 g: 625 g

2/50=25/625

1/25=1/25

The extreme terms are 2kg and 625g. The mean terms and 50kg and 25g.

(d) 200 mL: 2.5 litre and ₹ 4: Rs 50

2.5 l= 2500 ml

200/2500=4/50

2/25=2/25

The extreme terms are 200ml and Rs 50. The mean terms and 2.5litre and ₹4.
