Question
Students seem to miss the fact that division is actually multiplication by the reciprocal or the inverse of multiplication. This question attempts to address that.

Question
This question is to test if you know how to use your calculator correctly.

Question
Some students believe a decimal is larger if it is longer, some believe a decimal is larger if its first nonzero digit is larger.

Question
I feel this question has too many questions inside it, I have since made a question that just asks a single division problem called Decimals: Division (includes rounding the answer).

Question
a) Multiplying decimals with a single nonzero digit. Students are told to preserve the number of decimal places (from the question to the answer).
b) Multiplying decimals requiring the multiplication algorithm.

Question
By powers of ten I mean a 1 followed by some 0s. The scientific notation questions will take care of the power of ten notation.

Question
Issues: alignment in columns in the working  not sure what to do about it
Decimal divided by a decimal. Multiply by a power of ten to get an integer divisor. Long division process. There is a remainder which we express as a decimal by continuing the long division process. Rounding is required to some number of decimal places.

Long division, two digit divisor results in a remainder, answer expressed as a decimal rounded to 1 decimal place Ready to useQuestion
Divisor is a double digit. There is a remainder which we express as a decimal by continuing the long division process. Rounding is required to one decimal place. The working suggests determining the second decimal place so the student knows whether to round up or down.

Question
old question, way too many things in one question! I have made better questions out of each part now.

Question
I think I prefer the other question I made called "Rounding to 0, 1, 2 and 3 decimal places"

Question
Round random numbers to the closest whole number, 1 to 3 decimals places. Also rounding that could show common misunderstandings.

Long division, single digit divisor results in a remainder, answer expressed as a decimal rounded to 1 decimal place Ready to useQuestion
Divisor is single digit. There is a remainder which we express as a decimal by continuing the long division process. Rounding is required to one decimal place. The working suggests determining the second decimal place so the student knows whether to round up or down.

Long division, two digit divisor results in a remainder, answer expressed as a terminating decimal Ready to useQuestion
Divisor is a double digit. There is a remainder which we express as a decimal by continuing the long division process. No rounding is required by design (another question will include rounding off).

Long division, single digit divisor results in a remainder, answer expressed as a terminating decimal Ready to useQuestion
Divisor is single digit. There is a remainder which we express as a decimal by continuing the long division process. No rounding is required by design (another question will include rounding off).

Long division, two digit divisor results in a remainder which is expressed as a fraction Ready to useQuestion
Divisor is double digit. There is a remainder which we express as a fraction.

Long division, single digit divisor results in a remainder which is expressed as a fraction Ready to useQuestion
Divisor is single digit. There is a remainder which we express as a fraction.

Question
Nice easy case except divisor is a double digit. There is no remainder.

Question
The simplest case. Divisor is single digit. There is no remainder.
