► Total number of blocks = 8
► Number of shaded blocks = 1
► Number of unshaded blocks = 7
⇒ Fraction of Shaded area = No. of shaded blocks/ Total number of blocks = 1/8.
Thus, the correct answer is Option B.
► Total number of blocks = 3
► Number of shaded blocks = 1
► Number of unshaded blocks = 2
⇒ Fraction of Shaded area = No. of shaded blocks/ Total number of blocks = 1/3.
Thus, the correct Option B.
► Total number of blocks = 8
► Number of shaded blocks = 7
► Number of unshaded blocks = 1
⇒ Fraction of Shaded area = No. of shaded blocks/ Total number of blocks = 7/8
Thus the correct answer is Option C.
► (1/2) x (1/5) = 1/10
Thus, the correct answer is Option B.
► Total number of blocks = 8
► Number of shaded blocks = 4
► Number of unshaded blocks = 4
⇒ Fraction of Shaded area = No. of blocks of shaded area / Total number of blocks = 4/8 = 1/2.
Thus, the correct answer is Option A.
► Total number of blocks = 6
► Number of shaded blocks = 4
► Number of unshaded blocks = 2
⇒ Fraction of Shaded area = No. of shaded blocks/ Total number of blocks = 4/6 = 2/3.
Thus, the correct answer is Option A.
When 0.232323..... is converted into a fraction, then the result is:
0.23232323…=
Let, x =
100x = 23.232323...
⇒ 100x  x = 23.232323......  0.23232323......
⇒ 99x = 23
⇒ x = 23/99
Thus, the correct answer is Option C.
Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is:
Let the three consecutive odd integers be x, x+2, x+4
Three times the first of three consecutive odd integers is 3 more than twice the third.
∴ 3x=2(x+4)+3
∴ x=11
Hence, the third integer is 11+4=15.
Thus, the correct answer is Option D
Given: 2994 ÷ 14.5 = 172
29.94 ÷ 1.45 = 2994 ÷ 145
Thus, the correct answer is Option C.
► 0.01 × 0.01 = 0.0001
Thus, the correct answer is Option A.
Arrange the following in descending order:
(2/9), (2/3), (8/21)
First, we convert each fraction into a like fraction.
► 2/9 = (2 x 7)/(9 x 7) = 14/63
► 2/3 = (2 x 21)/(3 x 21) = 42/63
► 8/21 = (8 x 2)/(21 x 3) = 24/63.
If denominators are the same, then, greater the numerator, the greater will be the fraction.
∵ 42 > 24 > 14
⇒ (2/3) > (8/21) > (2/9)
Thus, the correct answer is Option A.
Ritu ate 3/5 part of an apple and the remaining apple was eaten by her brother Somu. How much part of the apple did Somu eat?
► Side of square = 2/a
⇒ Perimeter = 4 x side of square = 4 x 2/a = 8/a
Thus the correct answer is Option D.
Given numbers are: 0.3 , 3 , 0.03 and 0.002
► Average = Sum of numbers divided by total numbers
⇒ Average = (0.3 + 3 + 0.03 + 0.002)/4 = 3.332 / 4 = 0.833
Thus, the correct answer is Option A.
The result of adding the difference of 3.003 and 2.05 to their sum is:
Given numbers are: 3.003 and 2.05
► Sum of numbers = 3.003 + 2.05 = 5.053
► Difference of numbers = 3.003  2.05 = 0.953
Adding the Difference of numbers to the Sum of numbers, 5.053 + 0.953 = 6.006
Thus, the correct answer is Option A.
Find the area of rectangle whose length is 6.7 cm and breadth is 2 cm.
Given: Length, L = 6.7 cm, Breadth, B = 2 cm
► Area of rectangle = L x B = 6.7 x 2 = 13.4 cm^{2}
Thus, the correct answer is Option B.
43m = 0.086
⇒ m = 0.086/43 = 0.002.
Thus, the correct answer is Option A.
► (3/5) of 25= (3/5) x 25 = 3 x 5 = 15.
Thus, the correct answer is Option C.
► (5/7) ÷ (1/2) = (5/7) x (2/1) = 10/7
Thus, the correct answer is Option C.
A fraction in which the numerator is greater than the denominator is called an improper fraction.
Option A: 20 is less than 70
Option B: 30 is less than 40
Option C: 50 is greater than 20
Option D: 70 is less than 80
Thus, option C is the correct.
Which of the following is an equivalent fraction of 3/10?
Two fractions are said to be equivalent fractions if the simplest form of both the fractions is the same.
Option A: 6/20 = 3/10
Option B: 5/20 = 1/4
Option C: 1/40 = 1/40
Thus option A is correct.
► (2/3) of 66 = (2/3) x 66 = 44
Thus, the correct answer is Option D.
The product of two proper fractions is ______ than each of the fractions that are multiplied
The product of two proper fractions is less than each of the fractions that are multiplied.
Example: 1/2 x 1/4 = 1/8
1/8 < 1/2 and 1/8 < 1/4.
Thus, the correct answer is Option B.
► Divide whole of the fraction 2/4 by 2, we get 1/2.
Thus, the correct answer is Option B.
► 2.05 x 1.3 = 2.665
Thus, correct answer is Option A.
