-7/10 divided by 2/5 is -35/20 or -7/4 in the simplest form
-1/4 times (-4/3) is 4/12 or 1/3 in the simplest form
-3 1/3 or -10/3 times by -2 7/10 or -27/10 is 270/30 or 9
-10 2/7 or -72/7 divided by -4 4/11 or -48/11 is 792/336 or 33/14 in the simplest from
The sinusoid makes a complete oscillation (i.e. 360°) every 3 seconds. So, in one second it makes 1/3 of a turn, leading to 360°/3 = 120°.
So, the correct answer is the last one.
Your answer would be 34%,i hope this helps
