Respuesta :

4/1*2/3=simple multiplcation. numerator times numerator and denom. times denom. Then simplify or change to mixed fraction.

1/2 times 16 is basically 16/2. 16*1/2

For the Practise questions, any number 5 or greater-->round up 1
                                            any number 4 or less-->stays the same.
EX: 4.67-->5, cuz .6 is greater than 5.
EX: 3,26-->3, cuz 2 is less than 6

Keeping that in mind will help you easily estimate those answers without doing a lot of thinking:)



Number 1 is 2 2/3 and Number 2 is 8
