Write each of the following as decimals. (a) Seven-tenths (b) Two-tens and nine-tenths (c) Fourteen point six (d) One hundred and two ones (e) Six hundred point eight

Answer:

(a) Seven-tenths \[1\times 100+0\times 10+2\times 1+6\times \frac{1}{10}+3\times \frac{1}{100}+0\times \frac{1}{1000}\] (b) Two-tens and nine-tenths\[=100+0+2+\frac{6}{10}+\frac{3}{100}+0=102+\frac{6}{10}+\frac{3}{100}\] \[=102+0.6+0.03=102.63\] (c) Fourteen point six = 14.6 (d) One hundred and two ones\[0\times 100+3\times 10+0\times 1+0\times \frac{1}{10}+2\times \frac{1}{100}+5\times \frac{1}{1000}\] \[=0+30+0+0+\frac{2}{100}+\frac{5}{1000}\] (e) Six hundred point eight = 600.8
