#1 answers are 115 times 10 equals 1150 hm.
115km times 100 equals 11500dam.
115km times 1000 equals 115000m.
#2 is 418 divided by 10 equals 41.8.
418 divided by 100 equals 4.18
418 divided by 1000 equals 0.418.
#3 is 40 cm= 400mm
#4 is 500 ml= 5dl
#5 is 6kg= 6000g
#6 is 5000cl=50 l.
#7 is 4 kg=40 hg.
#8 is 200 mm = 20cm
You would multiply -2 by 11 and get -22. Next your equation would equal to -22+9y=5. You simply subtract -22 from both sides, which basically means you're adding 22. Next your equation would be 9y=27. All that is left to do is divide both sides by 9, and you get that y is equal to 3.
