Trevor has 12 2/5 to plant vegetables. he used 1/5 of the acres for corn and 1/3 of the acres for tomatoes.

a) how many acres does trevor use to plant corn? show your work.

b)how many acres does trevor use to plant tomatoes? show your work.

OK so first let's turn 12 2/5 into a decimal which would be 12.4. then take 12.4 and multiply it by .2 or 1/5 and you should get 2.48 which in a fraction is 2 48/100 which can be reduced to 2 12/25.

for the next one you would still use 12.4 and you multiply that by 1/3 or if you want to make it easier just divide by 3 and you get 4.13 with 3 repeating so in your case just round to the hundredths and keep it as 4.13 when converted to a fraction it will be 4 13/100 so the answer is 4 13/100.

hope this helps

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
