Introduction to grade 7 math fractions:
A fraction is a part of a whole. Fractions consist of two numbers. The top number is called the numerator. The bottom number is called the denominator. The denominator of a fraction is the number that shows how many equivalent parts are in the entire measure. The numerator of a fraction is the number that shows how many equal parts of the, whose are taken.
Numerator
denominator
In a fraction, if the numerator is smaller than the denominator, it is called as proper fraction. Proper fractions are in completely reduced form. If the numerator is bigger than the denominator, these types of fractions are called as improper fractions. If a fraction is constructed by a whole number and a proper fraction is called as mixed fraction.
For example, 2/3 is a proper fraction (2 < 3), 5/3 is an improper fraction (5 > 3), 2 1/3 is a mixed fraction (2 is a whole number, 1/3 is a proper fraction)
Grade 7 math fractions – Mixed fraction and improper fraction:
Grade 7 math fraction - Express mixed number as improper fraction:
Procedure: To express a mixed number as an improper fraction
Multiply the whole number by the denominator.
Add the numerator to obtain the numerator of the improper fraction.
The denominator is the same as that of the original fraction.
Example problems:
Problem 1:
Express 4 ½ as an improper fraction
Solution:
Multiply the whole number by the denominator.
Add the numerator to obtain the numerator for the improper fraction.
= (4 * 2 + 1) / 2 = (8 + 1) / 2
The denominator is the same as that of the original fraction.
= 9 / 2
Grade 7 math fraction - Expressing improper fraction as mixed number:
Procedure: To express an improper fraction as a mixed number
Divide the numerator by the denominator
Example problems:
Express the following improper fractions as mixed numbers
15 / 4 = 3 3/4
43 / 3 = 14 1/3.

Grade 7 math fractions – Mixed fraction and decimal:
Grade 7 math fraction - Decimal to mixed fraction steps with example:
Problem:
0.56 to mixed fraction
Solution:
Here's convert 0.56 to a mixed fraction, means. Since there are 2 digits in 56, the very last digit is the "100th" decimal place. So we can just say that 0.56 is the same as 56/100.
The fraction 56 /100 is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 4.
Divide by 4, 4 is the Greatest Common Divisor (GCD) of the numbers 56 and 100. So, this fraction reduced to lowest terms is 14 /25 = -1 9/25. So your final answer is: 0.56 can be written as the fraction -1 9/25
Grade 7 math fraction- Mixed fraction to decimal steps with example:
Problem:
2 5/3 to decimal.
Solution:
A mixed number is a whole number and a fraction. In this problem mixed number will be 2 5/7
Change the mixed number into an improper fraction. This is done by multiplying the denominator by the whole number and then adding the numerator (2 * 7) + 5. This will be new numerator.
And the improper fraction with the new numerator on top and existing denominator on the bottom, the new fraction 19 / 7.
Divide the numerator by denominator. Add a decimal point after the whole number and continue to divide by adding zeros after the decimal as needed. Then answer is 2.714, which can be rounded up to 2.7
Answer: So final answer 2.7
