Grade 5 Math Online Worksheet with Answers :
In this section, we will see some practice problems for 5th grade students.
Question 1 :
The value of 25 factorial divided 24 factorial is
(A) 25 (B) 30 (C) 45
Solution :
25!/24! = (25 x 24!) / 24!
= 25
Question 2 :
Find the perimeter in inches of a square that has area 49 ft2
(A) 450 inches (B) 125 inches (C) 336 inches
Solution :
Area of square = 49 ft2
a2 = 49
a = 7
Perimeter of square = 4a
= 4(7)
= 28 inches
Question 3 :
Kevin's garden measures 13 by 25 feet. What is the area of Kevin's garden, in ft2 ?
(A) 132 ft2 (B) 150 ft2 (C) 325 ft2
Solution :
Length of the garden = 13 ft
width of the garden = 25 ft
Area of the garden = length x width
= 13 x 25
= 325 ft2
Question 4 :
The area of triangle ABC is 35. If BC = 10, then find the height from A to BC
(A) 5 (B) 7 (C) 3.
Solution :
Area of the triangle = 35
(1/2) ⋅ base ⋅ height = 35
base = 10
(1/2) ⋅ 10 ⋅ height = 35
height = 35 / 5
height = 7
Question 5 :
What is the area of a square with a diagonal of length 50 cm ?
(A) 5 cm2 (B) 25 cm2 (C) 10 cm2
Solution :
Length of the diagonal = 50 cm
In a square the length of all sides will be equal. The diagonal divides the square into two right triangles.
a2 + a2 = 50
2a2 = 50
a2 = 25
a = 5
Area of square = a2
= 52
= 25
Question 6 :
What is the least number which when divided by 15, 20, 25 and leaves a remainder 10 ?
(A) 310 (B) 300 (C) 450
Solution :
We can find the least number when divided by 15, 20 and 25 leaves the remainder 0 by finding the least common multiple of given numbers.
Least common multiple of (15, 20 and 25) is 300
But the common number should leave the remainder 10.
300 + 10 = 310
Hence 310 is the least number that divides the given numbers by leaving the remainder 10.
Question 7 :
If 1 − 7x = 2x, then what is x?
(A) 1/5 (B) 1/10 (C) 1/9
Solution :
1 = 2x + 7x
9x = 1
x = 1/9
Hence the answer is 1/9.
Question 8 :
Subtract 546.925 - 52.68
(A) 494.245 (B) 124.245 (C) 505.212
Solution :
546.925 - 52.68 = 494.245
Question 9 :
What is the distance from the point (0, 2) to the point (0, 6) ?
(A) 4 units (B) 7 units (C) 5 units
Solution :
Distance between two points = √(x2 - x1)2 + (y2 - y1)2
= √(0 - 0)2 + (2 - 6)2
= √(-4)2
= 4 units
Question 10 :
Simplify 2a + 2a - 8a
(A) -a (B) -4a (C) 12a
Solution :
2a + 2a - 8a
= 4a - 8a
= -4a
-4a is the answer.
