followed by 25 and 50 paisa coins in 1963.

The government of Pakistan issued its first coins in 1948

Explanation

If you divide a decimal by 10, the decimal point will move one place to the left.

0.7 / 10 = 0.07

Explanation

0.05 is equivalent to the fraction 1/20 because 0.05 is the same as 5/100, which simplifies to 1/20.

Explanation

0.005 × 0.2 = 0.001

So, the product of 0.005 and 0.2 is 0.001.

Explanation

• To convert a decimal to a percentage, multiply by 100:
  

$0.09\times 100=9\mathrm{\%}$

Explanation

Half of 1 percent is:

(1/2) x 1% = (1/2) x 0.01 = 0.005

Explanation

To find the percentage, divide 25 by 75 and multiply by 100:

25 ÷ 75 = 0.33

0.33 × 100 = 33%

Explanation

To divide a number by 100, you can simply move the decimal point two places to the left:

0.26 ÷ 100 = 0.0026

Explanation

Note that the BCD code is 12 bits long since each of the decimal digits is coded by four bits.

Explanation

Conversion of binary (101011) to decimal:

Write the binary digits with powers of 2:

1×2⁵ + 0×2⁴ + 1×2³ + 0×2² + 1×2¹ + 1×2⁰

= 32 + 0 + 8 + 0 + 2 + 1

= 43

So, binary (101011) = decimal 43.
