Grade 5 Number Work

Step 1: Read the number by placing commas according to the Indian system (starting from the right: ones, tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, crores). The number is 74,52,981.

Step 2: Read the number in each period (groups of digits separated by commas) from left to right.
- The digits before the first comma (from the left) are 74, which are in the Lakhs period. So, "Seventy-four Lakh".
- The digits between the first and second comma are 52, which are in the Thousands period. So, "fifty-two Thousand".
- The digits after the second comma are 981, which are in the Units period. So, "nine hundred eighty-one".

Step 3: Combine the parts, adding the period names: Seventy-four Lakh fifty-two Thousand nine hundred eighty-one.

Step 4: Therefore, the number 74,52,981 in words is Seventy-four Lakh fifty-two Thousand nine hundred eighty-one.

Step 1: Identify the place value of each digit in the number 5,93,045.
- 5 is in the Lakhs place (1,00,000)
- 9 is in the Ten Thousands place (10,000)
- 3 is in the Thousands place (1,000)
- 0 is in the Hundreds place (100)
- 4 is in the Tens place (10)
- 5 is in the Ones place (1)

Step 2: Multiply each digit by its place value.
- 5 × 1,00,000 = 5,00,000
- 9 × 10,000 = 90,000
- 3 × 1,000 = 3,000
- 0 × 100 = 0
- 4 × 10 = 40
- 5 × 1 = 5

Step 3: Write the number as the sum of the products from Step 2.
5,93,045 = 5,00,000 + 90,000 + 3,000 + 0 + 40 + 5

Step 4: Therefore, the expanded form of 5,93,045 is 5,00,000 + 90,000 + 3,000 + 40 + 5. (You can omit the term with 0).

Step 1: Identify the place value represented by each term in the expanded form.
- 8,00,000 is 8 Lakhs
- 50,000 is 5 Ten Thousands
- 7,000 is 7 Thousands
- 200 is 2 Hundreds
- 10 is 1 Ten
- 6 is 6 Ones

Step 2: Place the digit corresponding to each place value in its correct position. If a place value is missing in the expanded form, put a 0 in that place.
Lakhs: 8
Ten Thousands: 5
Thousands: 7
Hundreds: 2
Tens: 1
Ones: 6

Step 3: Combine the digits to form the number, using commas according to the Indian system.
The digits are 8, 5, 7, 2, 1, 6.
Arranging them from left to right: 857216.
Placing commas: 8,57,216.

Step 4: Therefore, the number for the expanded form 8,00,000 + 50,000 + 7,000 + 200 + 10 + 6 is 8,57,216.
