Write each of the following as decimals.
(a) $ 20+9+\frac{4}{10}+\frac{1}{100} $
(b) $ 137+\frac{5}{100} $
(c) $ \frac{7}{10}+\frac{6}{100}+\frac{4}{1000} $
(d) $ 23+\frac{2}{10}+\frac{6}{1000} $
(e) $ 700+20+5+\frac{9}{100} $
To do:
We have to express the given expressions as decimals.
Solution:
(a) $20+9+\frac{4}{10}+\frac{1}{100}$
$=20+9+0.4+0.01$
$=29.41$
(b) $137+\frac{5}{100}=137+0.05$
$=137.05$
(c) $\frac{7}{10}+\frac{6}{100}+\frac{4}{1000}=0.7+0.06+0.004$
$=0.764$
(d) $23+\frac{2}{10}+\frac{6}{1000}=23+0.2+0.006$
$=23.206$
(e) $700+20+5+\frac{9}{100}=700+20+5+0.09$
$=725.09$
