So 20=2 itmes m2 times 5
5m=5 times m
so
5m=20
5 times m=2 times 2 times 5
divid eboth sides y 5
m=2 times 2
m=4
167 divided by 100 = 1.67
1.67 x 14.5= 24.215
answer to nearest tenth = 24.2
Im 99.99999% it is the top left
−3/4+(1/10÷2/5)
parenthesis first
1/10 divided by 2/5
copy dot flip
1/10 * 5/2
5/20
1/4
−3/4+(1/10÷2/5)
-3/4 + 1/4
-2/4
divide top and bottom by 2
-1/2
Yes it is already simplified because there is nothing else that you are able to do to it.
