What is the area fraction?
A fraction area model shows a whole shape split into equal parts. Count the number of equal parts in the whole shape.
Can I simplify this fraction?
In order to simplify a fraction there must be: A number that will divide evenly into both the numerator and denominator so it can be reduced, or. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number.
How do I multiply a fraction by a whole number?
You can follow these steps to multiply a fraction by a whole number:
- Write the whole number as a fraction with a denominator of 1.
- Multiply the numerators.
- Multiply the denominators.
- Simplify. , if needed. If your answer is greater than 1, you may want to write your answer as a mixed number.
How do you solve fractions?
To add fractions there are Three Simple Steps:
- Step 1: Make sure the bottom numbers (the denominators) are the same.
- Step 2: Add the top numbers (the numerators), put that answer over the denominator.
- Step 3: Simplify the fraction (if needed)
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.
What is a positive times a positive?
Rule 1: A positive number times a positive number equals a positive number. This is the multiplication you have been doing all along, positive numbers times positive numbers equal positive numbers. For example, 5 x 3 = 15. 5 is a positive number, 3 is a positive number and multiplying equals a positive number: 15.
Do 2 positives make a positive?

How do you find the sum of negative and positive numbers?
To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero.
What happens when you add a positive to a negative?
Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.
When the signs are the same you add?
To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
