Maths Quiz - Multiplication and Division (Difficult) (Questions)

Symbols are used for multiplication and division in mathematical equations. The x denotes multiplication and the ÷ denotes division. This 11-plus Maths quiz is the first in our series of difficult quizzes on multiplication and division. Remember to look at all four answers before making your choice. Here's a reminder of two useful tips:

To multiply a number by another number which is a multiple of 10 and whose only non zero digit is the leading digit 1: move the digits to the left by the same number of zeros that are in the multiple of 10. Note: whole numbers that do not have decimal parts are written without a decimal point e.g. 400.0 = 400: in such cases the d.p. is not normally needed.
To divide a number by another number which is a multiple of 10 and whose only non zero digit is the leading digit 1: move the digits to the right by the same number of zeros that are in the multiple of 10.
