Question

Write as decimal numbers.

A.$70+3+\frac{2}{100}+\frac{7}{1000}$

B.$5000+400+30+2+\frac{1}{10}+\frac{2}{100}$

C.$256+\frac{7}{1000}$

D.$\frac{7}{10}+\frac{3}{100}+\frac{5}{1000}$

Answer 1

$\left(a\right)70+3+\frac{2}{100}+\frac{7}{1000}$

$=70+3+0.02+0.007=73.027$

$\left(b\right)5000+400+30+2+\frac{1}{10}+\frac{2}{100}$

$=5000+400+30+2+0.1+0.02=5432.12$

$\left(c\right)256+\frac{7}{1000}$

$=256+0.007=256.007$

$\left(d\right)\frac{7}{10}+\frac{3}{100}+\frac{5}{1000}$

$=0.7+0.03+0.005=0.735$
