Question

Three of the choices are ways to express 0.50. Which is NOT?

Answer 1

Option B

5 hundredths is not the way to express 0.50

Solution:

Given that Three of the choices are ways to express 0.50

To find: wrong option

Let us first write 0.50 in different ways

To convert a Decimal to a Fraction follow these steps:

Step 1: Write down the decimal divided by 1, like this: decimal 1.

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. ...

Step 3: Simplify (or reduce) the fraction.

$\rightarrow 0.50 = \frac{0.50 \times 100}{100} = \frac{50}{100}$

$\frac{50}{100}$ means 50 hundredths

Therefore option D is correct

On simplifying $\frac{50}{100}$ we can write,

$\rightarrow \frac{50}{100} = \frac{5}{10} = \frac{1}{2}$

$\frac{1}{2}$ means one half

Therefore option A (one half) is correct

Similarly, \frac{5}{10} means 5 tenths

Therefore Option C is also correct

Thus the wrong option is B

Justification:

5 hundredths can be written as:

$\frac{5}{100} = 0.05$

Therefore option B is wrong
