Multiplying by multi-digit numbers is similar to multiplying by two-digit numbers in that both processes involve breaking down the numbers into place values and multiplying each digit by each digit in the other number. The key similarity lies in the application of the distributive property, where each digit in one number is multiplied by each digit in the other number, and then the products are added together to get the final result. This process is consistent whether you are multiplying by a two-digit number or a multi-digit number.
You simply multiply the two numbers together ignoring the decimal point. You then count the number of decimal places in each of the multiplicands and add them together. In the product, you put the decimal point so that there as many digits after the decimal point as that sum.For example, to multiply 2.63 by 3.271263 * 3271 = 860273.There are 2 digits after the decimal point in the first multiplicand and 3 in the second. 2 + 3 = 5So the decimal point in the answer is placed so that there are 5 digit after it: 8.60273
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.

Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.

All whole numbers are decimal numbers.
did you get this off of big ideas learning
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.

You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
