$27.64×3 =82.92
answer=$82.92
Ok. Since the fractions aren't the same, we have to make them common. They both have 30 in common.
4/10 = 12/30 I multiplied this 4 by 3 since I did 10 times 3.
2/3 = 20/30 Same with this one. Since 3 times 10, 2 times 10
Now you add the things to get 32/30, simplify to 1 2/30, and again to get 1 1/15.
Now add
3+2+1/15 = 6 1/15
He used 6 1/15 bags of fertilizer.
The answer is b.6 hope that helps :)
Set up conversion problems so that you can cancel out units that you don't want and introduce units that you do want for your final solution.
5w(m/3w)=15m
So you will need 15 cups of milk if 5 cups of water are used.
