Question

pls can anyone give me the full explanation​

Answer 1

Answer:

price of 1 rupee = 100 paisa

so,

7 rupee = 7 × 100 paisa

then,

19.81 rupee = 19.81 ×100

and

2 1/2 = 2 ×2 +1 = 5 by 2 rupee = 5÷2 ×100 = 500 ÷ 2 paisa = 250 paisa

Answer 2

Answer:

= 250p

Step-by-step explanation:

2 1/2 = convert into improper fraction. first step

=2×2+1

=5/2

100p= 1 rupee ,so for converting into paise we must subtract it with 100. second step

=5/2 × 100

= 5/1×50. (by cancelling)

= 5×50. (we can cancel the numbers 2 and 100 ,2×1 ,2×50)

note:we can only cancel numerator and denominator,or denominator and numerator ,(only opposite )

= so the answer is 5×50=250 final step
