Students find the missing number in decimal multiplication in multiply tenths less than 1 and multiples of 100 worksheet. To do this, they apply the understanding that when multiplying a decimal by a number that ends in zeros, the decimal point will be moved to the right by the same number of places as the multiplier's number of zeros. 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.
