Question

What is the value of $\frac{5}{1000} + \frac{2}{100} + \frac{1}{10}$?

• A. 0.521
• B. 0.125
• C. 0.8
• D. 0.008

Answer 1

Answer:

B. 0.125

The answer is 0.125 (or 1/8 in fraction form).

Method 1: Convert to Decimals (Easiest)

• $\frac{5}{1000} = 0.005$

• $\frac{2}{100} = 0.02$

• $\frac{1}{10} = 0.1$

Now, add them up by lining up the decimal points:

  0.005
  0.020
+ 0.100
-------
  0.125

Method 2: Common Denominator
Make the denominators the same (1000):

• $\frac{1}{10} = \frac{100}{1000}$

• $\frac{2}{100} = \frac{20}{1000}$

• $\frac{5}{1000} = \frac{5}{1000}$

Now, add the numerators together:
$\frac{5 + 20 + 100}{1000} = \frac{125}{1000}$

If you simplify $\frac{125}{1000}$ by dividing both the top and bottom by 125, you get $\frac{1}{8}$, which is exactly 0.125.
