Question

Find the decimal form of the sum 1/2+1/2 sq.+1/2 cube

Answer 1

To find:

The decimal form of the sum $\dfrac{1}{2}+\dfrac{1}{2^{2}}+\dfrac{1}{2^{3}}$

Step-by-step explanation:

The solution of this problem becomes easier when you convert each fraction into decimal numbers.

• $\dfrac{1}{2}=0.5$

• $\dfrac{1}{2^{2}}=\dfrac{1}{4}=0.25$

• $\dfrac{1}{2^{3}}=\dfrac{1}{8}=0.125$

Therefore, $\dfrac{1}{2}+\dfrac{1}{2^{2}}+\dfrac{1}{2^{3}}$

$=0.5+0.25+0.125$

$=0.875$

Answer:

$\quad \boxed{\dfrac{1}{2}+\dfrac{1}{2^{2}}+\dfrac{1}{2^{3}}=0.875}$

NOTE:

We can also find the solution by adding the fractions.

$\quad \dfrac{1}{2}+\dfrac{1}{2^{2}}+\dfrac{1}{2^{3}}$

$=\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{8}$

$=\dfrac{4+2+1}{8}$

$=\dfrac{7}{8}$

$=0.875$
