To reduce a fraction, divide both the numerator and denominator by the GCF. (This is also known as "writing a fraction in lowest terms".) This is sometimes shown as "canceling" the common factors. Note that the result is an equivalent fraction in simplest form.
So, reducing or simplifying fractions means we make the fraction as simple as possible. We do this by dividing the numerator and the denominator by the largest number that can divide into both numbers exactly. In other words, we divide the top and bottom by the biggest number they have in common.
For example, the fraction 2/3 is fully reduced. There isn't any whole number, other than 1, that both 2 and 3 can be divided by without having a remainder. Other examples of fully reduced fractions include 7/8, 5/9, and 11/20. An example of a fraction that isn't fully reduced is 2/4.
A fraction written in lowest terms, i.e., by dividing numerator and denominator through by their greatest common divisor. . For example, 2/3 is the reduced fraction of 8/12.
Step 1: Write the factors of numerator and denominator. Step 2: Determine the highest common factor of numerator and denominator. Step 3: Divide the numerator and denominator by their highest common factor (HCF). The fraction so obtained is in the simplest form.
If either numerator or denominator of a fraction is a prime number then the fraction cannot be simplified further. A fraction that has 1 in the numerator cannot be reduced further.
A fraction is written in lowest terms when it uses the smallest possible numerator and denominator. To put a fraction in lowest terms, find the largest number that divides both the numerator and the denominator. Divide both the numerator and the denominator by that number.
In fractions that cannot be reduced (fractions in lowest terms), the numerator and the denominator share no common factors; that is, they are relatively prime. To write a fraction in lowest terms, factor the numerator and the denominator. Then divide both the numerator and the denominator by the greatest common factor.
Thus, 40% as a fraction in simplest form is 2/5.
Answer: The value of 4% as a fraction in simplest form is 1/25.
Step 1: Write the factors of the numbers which are there in numerator and denominator. Step 2: Identify the common factors of both numerator and denominator. Step 3: In this step, we have to divide the numerator and denominator by the common factors until they have no common factor other than 1.
Cross-cancellation is a simplification that can be done before. That's great, because simplifying before means when you do multiply, you'll have smaller numbers, and smaller numbers are easier to work with. Did you catch that? Cross-cancellation makes fractions easier.
The Common Core Standards has made simplifying fractions a 4th grade math standard. When teaching this standard I realized that my students must understand that a fraction can be decomposed into units that make up the whole fraction.
