Test: Operations on Large Numbers- 1 - Question 1

Which of the following property of multiplication is shown in the statement given below?
3 x 6 = 6 x 3

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 1

Commutative property: We can multiply in any order and get the same product.

Test: Operations on Large Numbers- 1 - Question 2

The correct order to apply operations is

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 2

According to BODMAS, the correct order of operations is Division - Multiplication - Addition - Subtraction.

Test: Operations on Large Numbers- 1 - Question 3

96 ÷ 2 = 48 is not equivalent to

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 3

96 ÷ 2 = 48, Now evaluating the options, we get, 2 x 24 = 48, 4 x 12 = 48, 8 x 6 = 48 and 7 x 8 = 56. 
Thus the solution other than 48 is the odd one out. Therefore is the odd one out.

Test: Operations on Large Numbers- 1 - Question 4

Which of the following equation shows the identity property of addition?

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 4

Identity property: t = 0 + t, Adding zero does not change a number. Here 0 + 3 = 3 shows the identity property where adding zero does not change the sum.

Test: Operations on Large Numbers- 1 - Question 5

What should be subtracted from 14y to get 8 as answer?

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 5

Let 'a' be subtracted from 14 y to get 8. Then, 14y - a = 8 ⇒ a = 14y - 8.

Test: Operations on Large Numbers- 1 - Question 6

If 4a + 3 = 15 then the value of 2a is

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 6

4a + 3 = 15 
⇒ 4a = 15 - 3 = 12 
⇒ a = 12 ÷ 4 = 3
∴ 2a = 2 x 3 = 6

Test: Operations on Large Numbers- 1 - Question 7

86 - 23 = ? Which of the following statement is not equivalent to given statement?

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 7

86 - 23 = 63, Now evaluating the options, we get 7 x 9 = 63, 3 x 21 = 63, 45 + 18 = 63 and 187 ÷ 2 = 62.333. Thus the solution other than 63 is the odd one out. Therefore is the odd one out.

Test: Operations on Large Numbers- 1 - Question 8

Which equation shows the commutative property of addition?

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 8

Commutative property: r + s = s + r
We can add numbers in any order and get the same sum.
Here 8 + 4 = 4 + 8 shows the commutative property.

Test: Operations on Large Numbers- 1 - Question 9

Look at these numbers: 0.7, 0.5, 0.8, 0.7 Which two numbers in the box have a difference of 0.3?

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 9

Look for numbers in the box that are greater than 0.3.

  • Try 0.7. What number can you subtract from 0.7 to get 0.3? 0.7 - 0.4 = 0.3
    0.4 is not in the box.
  • Try 0.5. What number can you subtract from 0.5 to get 0.3? 0.5 - 0.2 = 0.3, 0.2 is not in the box.
  • Try 0.8. What number can you subtract from 0.8 to get 0.3? 0.8 - 0.5 = 0.3
    0.5 is in the box. The numbers 0.8 and 0.5 have a difference of 0.3.
Test: Operations on Large Numbers- 1 - Question 10

If  20 x 2.5 = 50 then 2 x 0.0025 = ?

Detailed Solution for Test: Operations on Large Numbers- 1 - Question 10
