You just move the decimal place over twice. Ex: 76% = 0.76
Number 2 would be b. 7/12= 0.583 repeating
To compare fractions, we need to have the same denominator
The least common multiple is
16
to change

, we should multiply the numerator and denominator by
4

=


<

so basically,

is greater than

which means

is greater

is greater
The andwer would be 136 beause you would have to multiply 9 and 10 to get its area in square feet, then you would have to add the answer to that problem(90) to 46 square feet, and your answer would be 136
Order doesn't mater so use combinations:
6C3 = 6!/ (3! (6-3)! ) = 6! /(3!*3!) = 6*5*4*3! / (3! 3!) = 6*5*4/3*2*1) = 20
