Answer 2

Step-by-step explanation:

a) 15% of 250

= 15/100 x 250

= 3/20 x 250

= 3 x 12.5

=37.5

b) 1 % of 1 hour

1 hr = 60 min

1 % of 60 min

= 1/100 x 60

= 0.6min

or

1 % of 1 hour

= 1/100 x 1hr

=1/100 hr

= 0.01 hr

c) 20% of Rs2500

= 20/100 x rs 2500

= 20 x rs25

=rs 500

d) 75% of 1 Kg

= 75/100 x 1kg

= 0.75 x 1kg

= 0.75kg

or

1kg = 1000g

75% of 1000g

= 75/100 x 1000g

= 75x 10g

=750g
