Decide whether -3/12 terminates or repeats when expressed as a decimal ​

Termintates

Step-by-step explanation:

It simplified is -.25, which, is a terminated decimal and does not repeat and go on

Terminates

Step-by-step explanation:

first the signs don't matter, just remember to put it back at the end

try dividing it:

3 / 12 = 0 with 30 tenths left over

30 / 12 = 2 with 60 hundreths left over

60 / 12 = 5 with 0 thousandths left over

no more remainders so it terminates

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
