You just do -52 divided by 4 and get -13 as your answer.
m = -14
$55 this is shown by doing 80/100=0.80. and 0.80*55=this is the answer
Divide 71 and 5 to get a decimal since 71 does not end with 5 or 0. Do it to get 14 1/5 or 14.2
M<7 + m<8 + m<9 = m<EAD
31 + 22 + m<9 = 102
53 + m<9 = 102
m<9 = 49
