Question

Express percentage
90cmas 4.5 m
40p as 2RS
500g as 6kg
40s as 6min

Answer 1

Answer:

1)20%

2)20%

3)8.33%

4)11.11%

Step-by-step explanation:

1)((90/100)/4.5)*100 =20%

2)(40/100)/2)*100 =20%

3)(500/1000)/6)*100 =8.33%

4)(40/60)/6)*100 =11.11%

Answer 2

BASIC INSTRUCTIONS

• First make both quantity same

a) 90 cm as 4.5 m

4.5 m = 4.5×100 = 450 cm

now,

x% of 450 cm is 90 cm

=>( x/100) ×450 = 90

=> x = 90 × 100/450

=> x = 20

so, 20% of 4.5 m is 90 cm

b) 40 p as 2 RS

2 RS = 2×100 = 200 p

now , x % of 200 p = 40 p

=> (x /100)×200 = 40

=> x = 40 × 100/200

=> x = 20

so, 20% of 2 RS is 40 p

c)6 kg = 6000 g

x% of 6000g is 500 g

=>( x /100 )× 6000 = 500

=> x = 500×100/6000

=> x = 8.33

so, 8.33% of 6 kg is 500 g

d) 6 min = 360 sec

40 s as 360 s

x%of 360 s = 40 s

=> (x/100)×360 = 40

=> x= 40×100/360

=> x = 11.11

so, 11.11% of 6min is 40 sec .
