 # Relative numbers: corrected 5th grade math exercises in PDF.

A series of exercises in fifth grade on relative numbers in math. Thus, these relative numbers are essential to the student’s learning in the field of mathematics. Indeed, they bring a lot of knowledge to the students and allow them to immerse themselves further. To this end, exercises on relative numbers are necessary for a good understanding of the chapter. Consequently, you will find in these exercises all the notions of this chapter taught in the fifth grade.

1. First, we have the definition of the relative number;
2. Then, the digital part;
3. Then, the graduated line and distance to zero;
4. In addition, there is the comparison of relative numbers;
5. Also, the coordinates of points in the plane;
6. Finally, addition and subtraction of relative numbers.

Then, in a second step, we will approach the addition and subtraction of relative numbers. Then we will end this lesson with concrete problems from everyday life in the seventh grade.

Indeed, in the fifth grade, we learned to work with numbers. In addition, we also learned how to perform mathematical operations. In addition, we studied relative numbers. However, it is important to know that these numbers can be positive, negative or zero.

### Exercise n°6 : relative numbers

Arrange the following relative numbers in descending order:

3,2 ; 2,7 ; – 5,2 ; – 2,7 ; 0 ; 3,26 ; 0,8 ; – 2,72 ; – 2,08

### Exercise n°7 relative numbers :

a) Arrange the following relative numbers in ascending order: 4.72; – 2.74; 4.702; – 2.704; 4.712; + 2.704

b) Arrange the following relative numbers in descending order: – 0,8; – 0,9 ; – 0,7; 0; – 1; +1; – 0,2; + 0,6 ; – 1,3

### Exercise #8 relative numbers :

Complete the boxes with a relative number that fits:

– 2 < ….. < 0 ; – 8,8 < ….. < – 7,7 ; – 3 < ….. < + 4 ; – 5 < ….. < – 4

– 6 < – 4 < ….. ; ….. < 2,8 < ….. ; ….. < – 26 < ….. ; – 9 < ….. < – 2

### Exercise n°9 relative numbers:

What are the relative integers verifying: – 3 < x < + 4 and – 6 < x < – 1

Exercise #10:

Determine the value of the following expressions:

A = (+27) – (+53) + (-2,9) – (+13,7)

B = (-25) – (-47) – (-17,7) – (+3,4)

C = (-13) – (+55) + 17 – 32 + 56 – 32 + 12,87

D = (-26 )+ (+ 75) – (+ 6) + (- 27) – (- 48)

### Exercise 11: relative numbers

A = (+503) – (-343,8) – (-415,5) – (743,8) + (-203) + (-84,5)

Thus, we need to calculate A by making clever groupings.

### Exercise #12:

Simplify and then calculate the value of A and B.

A = ( – 5 ) + ( 3 – 2 x 4 – 6 ) – ( – 12 )

B = (+ 7.4) – [2 + ( 3 – 4 x 2,6)]+ (-7) + (-11)

### Exercise #13:

Ramses II was a pharaoh born in -1304 and lived 67 years.

Ramses III lived 32 years and died in 1134 BC.

How many years separate the date of death of Ramses II from the date of death of Ramses III?
