Place value helps simplify the multiplication of a two-digit number by a multiple of 10 by allowing you to focus on the two-digit number first and then easily add the zero(s) associated with the multiple of 10. For example, when multiplying 23 by 40, you can first calculate 23 x 4, which equals 92, and then add one zero to get 920. This approach makes calculations easier and reduces the chances of errors. Understanding place value thus streamlines the multiplication process.
Simply move the decimal point one place to the RIGHT. For example 12.345 multiplied by ten - is 123.45.
Place value helps simplify multiplication by allowing you to break down the two-digit number and the multiple of ten into manageable parts. For example, when multiplying 23 by 40, you can first multiply 23 by 4 (which equals 92) and then add the appropriate number of zeros based on the place value of 40 (in this case, one zero). This method reduces complexity and makes calculations easier, leveraging the base-10 system effectively.
When you multiply a number by 10, you move the decimal point one place to the right. For example, if you have the number 3.5 and you multiply it by 10, it becomes 35. This shifting increases the value of the number, effectively scaling it up by a factor of ten.
Multiply by ten to move the decimal one place to the right. Multiply by 100 to move two places to the right. Divide by ten to move it one place to the left.
Multiply the number by 2 and then divide by 5 or, more simply, multiply by 4 and move the decimal point one place to the left.
Simply move the decimal point one place to the RIGHT. For example 12.345 multiplied by ten - is 123.45.
To calculate 12 x 90, you simply multiply the two numbers together. 12 x 90 = 1080. This is because when you multiply a two-digit number by a two-digit number, you multiply the ones place of the first number by the ones place of the second number, and then the tens place of the first number by the ones place of the second number, and so on.

To find the answer all you do is add a zero to the number.
When you multiply a number by 10, you move the decimal point one place to the right. For example, if you have the number 3.5 and you multiply it by 10, it becomes 35. This shifting increases the value of the number, effectively scaling it up by a factor of ten.
Multiply by ten to move the decimal one place to the right. Multiply by 100 to move two places to the right. Divide by ten to move it one place to the left.
To find 40% of a number, either multiply by .4 or multiply by 2 and divide by 5 or else multiply by 4 and move the decimal point one place to the left.
No. A number with multiple digits does not have a place value. A single digit in a multi-digit number has a place value.
Multiply the number by 2 and then divide by 5 or, more simply, multiply by 4 and move the decimal point one place to the left.
There is no greatest number. Whatever number you come up with, I can multiply it by 1000 and add 999 and create a larger number with a 9 in the hundreds place.
It is always zero !
An equivalent fraction is just a multiple of the one that you have (i.e it is the one that you have, scaled up or down). So multiply the fraction that you have until either the numerator or the denominator match the given numerator/denominator of the fraction with the missing number. The number in the corresponding place on the fraction that you multiplied is the missing number.
