Test: Operations on Large Numbers- 2 - Class 5 MCQ

3 x 15 = 45 and also 15 x 3 = 45. Thus A is true. 3 ÷ 2 = 1.5 and 2 ÷ 3 = 0.66 which are not equal. Therefore only statement A is true.

Mangoes in 100 boxes =
Mangoes in 1 box 
Mangoes in 75 boxes

Let the number of notes of each kind be x. Then 10x + 5x + 2x = 510 ⇒ x = 510 / 17 = 30.

No. of spoiled roses = 182039 ÷ 13 = 14,003

To solve 24 × 65, break it down into smaller parts:

• Calculate 24 × 5 = 120.
• Calculate 24 × 60 = 1440 (since 24 × 6 = 144, then add a zero for the tens place).
• Add the two results: 1440 + 120 = 1560.

Thus, the correct answer is C) 1560.

1042 multiplied by 5 equals 5210. Here is a step-by-step explanation:

• Multiply each digit of 1042 by 5 from right to left:
• 2 x 5 = 10 (write down 0, carry over 1)
• 4 x 5 = 20 + 1 = 21 (write down 1, carry over 2)
• 0 x 5 = 0 + 2 = 2
• 1 x 5 = 5
• Combining these results gives 5210.

To solve the equation, we simply add the two numbers together:

• First number: 881
• Second number: 88

Now, performing the addition:

Calculation:

881 + 88 = 969

Thus, the result of the equation is:

• Result: 969

To find the sum of 2547 and 9998, align them by place value and add each column from right to left:

  2547
+ 9998
-------
 12545

Starting from the units place:

• Units: 7 + 8 = 15 (write 5, carry over 1)
• Tens: 4 + 9 + 1 = 14 (write 4, carry over 1)
• Hundreds: 5 + 9 + 1 = 15 (write 5, carry over 1)
• Thousands: 2 + 9 + 1 = 12

Thus, the sum is 12545.

Look for numbers in the box that are less than 2.7.

• Try 0.2. Now we have to find the number which when added to 0.2 gives 2.7.
• That number is 2.5. thus 2.5 + 0.2 = 2.7.

To solve 428.65 + 500.50, follow these steps:

• Align the decimal points.
• Add each column starting from the rightmost digits.

When adding the cents:

• Add 65 and 50, which equals 115.
• This results in 15 cents with a carryover of 1.

Next, add the dollars including the carryover:

• Add 428 and 500 along with the carryover 1.
• This results in a total of 929.

Thus, the final total is 929.15.
