Find the Number Equal to the Fraction 3/20: Basic Value Recognition

Question

Which number is equal to $\frac{3}{20}$ ?

00:04 Let's change the fraction into a decimal.

00:08 First, make the fraction have one hundred on the bottom.

00:12 Multiply both the top and the bottom numbers. This is important!

00:18 Now, when you see one hundred on the bottom, the top is your decimal.

00:26 Remember, dividing by one hundred moves the decimal two spots left.

00:32 And there you have it! That's how you solve the question.

First we will multiply the numerator and denominator by a number that make the denominator 100.

$\frac{3\times5}{20\times5}=\frac{15}{100}$

Let's now rewrite the simple fraction as a decimal fraction:

$15.0$

Since we are dividing by 100, the decimal point will move two places to the left, giving us:

$.150$

Finally we will add 0 before the decimal point to get:

$0.150=0.15$

0.15
