Answer 1

Answer:

(1) 500/7

(2) ,100/3

Step-by-step explanation:

(a) find the ratio of 15kg to 210g?

Ans=Ratio of 15 kg to 210 g = 15kg/210 g = 15000g/210g = 500/7

(b) 9 m to 27 cm

⇒9×100 cm to 27 cm[∵1 m=100 cm]

⇒900 cm to 27 cm

Thus, ratio is =

900/27= 100/3

100/3 = 100:3

(c)570 lakhs km I don't know the answer correctly

(d) this answer is given in photo

(e) Rajastham

(f) sorry I don't know

(g) this is given in image above the answer

(h) In Rajasthan = \frac{570\ lakhs}{3\ lakhs\ per\ km^2}=190\ people\ km^2

3 lakhs per km

2

570 lakhs

=190 people km

2

In U.P. = \frac{1660\ lakhs}{2\ lakh\ per\ km^2}=830\ people\ per\ km^2

2 lakh per km

1660 lakhs =

1660 lakhs/2

=830 people per km
