How many fractions are equivalent to 4 5 explain?

How many fractions are equivalent to 4 5 explain?

As long as you multiply the numerator and denominator by the same number you can always find another equivalent fraction: ×33 is the same as ×1 , which does not change the value. 45×33=1215 or 45×88=3240 and so on ….

How do you write 5 divided by 8 as a fraction?

We can write 5 divided by 8 as 5 / 8.

How do you multiply fraction?

The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.

Why do you cross multiply fractions?

The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater. This is especially useful when you are working with larger fractions that you aren’t sure how to reduce. Let’s take a look at some numerical examples.

How do you simplify negative fractions?

Simplifying Negative Fractions

1. Step 1: Find the GCF of the numerator and denominator.
2. Step 2: Divide the numerator and denominator by the GCF.
3. Step 3: Place the negative sign back in front of the simplified fraction.
4. Step 1: Find the GCF of the numerator and denominator.

How do you turn a negative fraction into a positive?

One way is to multiply the denominator by . But that would change the number from a negative to a positive. If you just want your fraction to look different but represent the same number, you have to perform the same operation to the numerator that you perform to the denominator.

What is the rule for adding and subtracting fractions?

To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.

What is the rule for negative exponents?

Negative Exponent Rule: Only move the negative exponents. Product Rule: am ∙ an = am + n, this says that to multiply two exponents with the same base, you keep the base and add the powers.

Does flipping a fraction make it negative?

No, never. Flipping a fraction only affects the sign of the operation (from a division to a moltiplication) and switchs the numerator and the denominator of the second fraction. The minus sign (if you have it) remains, alway! No, the rule for division is that you multiply by the reciprocal.

What is a negative fraction?

– The negative of a number can be created by multiplying the number by negative one. These principles apply to fractions as well, so: Placing the negative sign before the entire fraction (subtracting the fraction) is equivalent to adding the same fraction, but with a negative numerator.
