Solution:
Question 2.
Write the numbers given in the following place value table in decimal form:
Solution:
(i) The number is 3 x 1 + 2 x \(\frac{1}{10}\) + 5 x \(\frac{1}{100}\) = 3 + 0.2 + 0.05 = 3.25.
(ii) Thenumberis 1 x 100 + 0 x 10 + 2 x 1 + 6 x \(\frac{1}{10}\) + 3 x \(\frac{1}{100}\)
= 100 + O + 2 + 0.6 + 0.03 = 102.63.
(iii) The number is 3 x 10 + 0 x 1 + 0 x \(\frac{1}{10}\) + 2 x \(\frac{1}{100}\) + 5 x \(\frac{1}{1000}\)
= 30 + 0 + 0 + 0.02 + 0.005 = 30.025.
(iv) The numberis 2 x 100+ 1 x 10 + 1 x 1 + 9 x \(\frac{1}{10}\) + 0 x \(\frac{1}{100}\) + 2 x \(\frac{1}{1000}\)
= 200 + 10 + 1 + 0.9 + 0.00 + .002 = 211.902.
(v) The number is 1 x 10 + 2 x 1 + 2 x \(\frac{1}{10}\) + 4 x \(\frac{1}{100}\) + 1 x \(\frac{1}{1000}\)
= 10 + 2 + 0.2 + 0.04 + 0.001 = 12.241.
