The correct work to find the product of 1.35 and 1.4 is:
1.35 × 1.4 = 1.89
To find the product of 1.35 and 1.4, you can follow these steps:
Step 1: Write down the numbers to be multiplied, one below the other, aligning the decimal points:
1.35
× 1.4
---------
Step 2: Multiply the numbers in the ones place (rightmost digit) just like you would in regular multiplication:
135
× 14
---------
Step 3: Start multiplying from the rightmost digit in the bottom number by the top number, carrying any excess digits to the next column:
Multiply 135 by 4: The result is 540.
Carry over the excess (5) to the next column.
---------
Step 4: Multiply the next digit in the bottom number by the top number:
135
× 1
---------
Multiply 135 by 1: The result is 135.
---------
Step 5: Add the partial products together, placing each product under the appropriate column:
135
× 14
---------
1890
+ 135
---------
Step 6: Add the partial products together to get the final product:
1.35
× 1.4
---------
1890
+ 135
---------
1890
+ 135
---------
1890
+ 540
---------
2,379
Therefore, the correct work to find the product of 1.35 and 1.4 is 2,379.
To find the product of 1.35 multiplied by 1.4, you can use the following steps:
Step 1: Multiply the decimals as if they were whole numbers.
1.35 × 1.4
Step 2: Ignore the decimal points for now and multiply the numbers.
135 × 14
Step 3: Multiply the units (ones place) and carry over any tens.
135
× 14
------
540 (multiplying the units place)
+1350 (multiplying the tens place)
------
1890
Step 4: Count the total number of decimal places in the original numbers.
In this case, there are two decimal places (1.35 has two decimal places, and 1.4 has one decimal place).
Step 5: Place the decimal point in the product by counting from right to left, starting from the rightmost digit of the solved problem. The decimal point should be placed that many places from the right.
1890 has no decimal point, so we will add it.
The final product of 1.35 × 1.4 is 1.89.
Therefore, the correct work to find the product is:
1.35 × 1.4 = 1.89
