ANSWER
1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
EXPLANATION
Renaldo wants to write
[tex] \frac{3}{20} [/tex]
as a decimal.
He needs a denominator of 100, so he can multiply by
[tex] \frac{5}{5} [/tex]
to obtain:
[tex] \frac{3}{20} = \frac{3 \times 5}{20 \times 5} [/tex]
This will be
[tex] = \frac{15}{100} [/tex]
He can now obtain the decimal equivalent as
[tex] = 0.15[/tex]
The correct choice is option 1.
Answer:
1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Step-by-step explanation:
Renaldo must use a method that does not alter the value of the original fraction. This means that by multiplying the fraction by a number, the result obtained remains the same as the initial number.
Then the fraction [tex]\frac{3}{20}[/tex] must be multiplied by the same number in the denominator and the numerator. For example:
[tex]\frac{3}{20}*\frac{5}{5}[/tex]
[tex]\frac{3}{20}*\frac{33}{33}[/tex]
If we multiply [tex]\frac{3}{20}*\frac{5}{5}[/tex] the result is:
[tex]\frac{15}{100}[/tex] To write this fraction in decimal form, we move the comma 2 digits to the left in the following way:
15.0 --------> 0.15.
Then [tex]\frac{15}{100}=\frac{3}{20}=0,15[/tex]
The answer is Option 1.
