Grade 9 Math

Introduction of grade nine fraction math:

The grade nine fraction maths is nothing but the fraction that involves the division, multiplication and subtraction. The grade nine fraction maths gives the most basic ideas of the fractions. Thus the fraction of the math gives the various topics and understandings of the math. The grade nine fraction math gives you various formation of the reduction of the fraction.

Grade nine fraction math:


Grade nine fraction math are the one which makes the form that gives the changes that shows the form in the fraction method. When the method gives the comparing of the two terms. The comparisons of the terms are the one which gives the changes that makes the form of the terms in the comparison of the two fractions. Hence we can find the largest and the smallest terms when compared between the two terms.


Examples for grade nine fraction math:


Example 1: Compare the two fractions 3/4 and 1/6?

Solution: When comparing the two fractions we found that 3/4 is greater than the 1/6.

Example 2: Compare the two fractions 4/5 and 2/2?

Solution: When comparing the two fractions we found that 4/5 is lesser than the 2/2.

Example 3: Compute the fractions with regrouping in the fractions like “1/80 + 4/80 + 9/80 + 6/80” is made to regrouping as “1/80+9/80 +6/80+4/80” the second terms are considered as simpler one these terms leads to the sum of ten [(1+9)/80, (6+4)/80] this made easier to keep the track off.

Example4: Compute the fractions with regrouping like “3x/80 + 2y/80 + 4x/80 + y/80 = 7” hence the regrouping of the x and y terms which can be made simpler.

This can be regrouped as 7x/80 + 3y/80 = 7.

Example 5: The 2 39 reduced to a fraction is obtained as the terms, 2/39 this terms can be prepared through the terms 2/39 = 2/39.

1) The given fraction 2/39 is not made to reduce to the lowest terms. Hence the fractions cannot reduce to the lowest terms.

2) The above terms cannot be reduced with the common terms.

Example 6: The 45 reduced to a fraction is obtained as the terms, 45/100 this terms can be prepared through the terms 45/100 = 9/20.

1) The given fraction 45/100 is not made to reduce to the lowest terms. Hence the fractions are reduced to the lowest terms.

2) The above terms can be reduced with the common terms like 5.

3) The value 5 is the greatest common divisor or the greatest common factor of the both numbers 45 and 100.

4) Hence the 45/100 can be reduced through the value five which results to the 9/20.
