Which of the following is the correct definition for an improper fraction?

Convert $$3 {{1} \over {3}}$$ into an improper fraction.

1 × 2 + $${2}\over{5}$$ × $${3}\over{4}$$

Which of the following is not a correct method for calculating $$1 {{2} \over {5}}$$ × $$4 {{3} \over {4}}$$?

Calculate $$2 {{3} \over {5}}$$ × $$3 {{2} \over {3}}$$.

Use the most efficient method to calculate $$5 {{1} \over {4}}$$ × $$1 {{3} \over {7}}$$.  Give your answer in its simplest form.

A number that has exactly 2 factors is a {{ }} number.

Which of the following will be less than 20?

$${2}\over{3}$$ × $${1}\over{8}$$is {{ }} than $${2}\over{3}$$ × $${1}\over{9}$$.

$${2}\over{85}$$ × $${25}\over{140}$$ = $${20}\over{5950}$$

$${4}\over{85}$$ ×  $${25}\over{140}$$ = $${50}\over{5950}$$

$${16}\over{85}$$ × $${25}\over{140}$$ = $${200}\over{5950}$$

$${20}\over{85}$$ × $${25}\over{140}$$ = $${250}\over{5950}$$

Using this fact, $${8}\over{85}$$ × $${25}\over{140}$$ = $${100}\over{5950}$$, which of the following are true?

Calculate $${2}\over{3}$$ × $${3}\over{4}$$ × 15.  Give your answer as a mixed number.

Calculate $${132}\over{385}$$ × $${15}\over{18}$$ by writing each numerator and denominator as a product of its prime factors.
