Students understand that multiplying a decimal by a number that ends in zeros causes the decimal point to be moved to the right by the same number of places as the multiplier's number of zeros. This understanding helps them find the missing number in multiply hundredths less than 0.1 And multiples of 100 worksheet. This worksheet is about practicing with the horizontal format in which numbers are written side by side. To develop flexibility with numbers and operations, students need to have enough practice in this format and not just rely on the vertical/column method.
