Question

Annabelle is designing a garden. She will plant 3/12 of the lot with daffodils, 1/6 with roses, and 3/12 with tulips. How much of the lot will be left to plant sunflowers

Answer 1

7/12 is left to plant sunflowers

Explanation:

Let's add

1/6+ 3/12

Our denominators don't match, so we can't add yet.

Since 6 is evenly divided by 12, we can multiply just one term to get a common denominator.

Multiply 1 by 2, and get 2, then we multiply 6 by 2 and get 12.

Add to get the amount of garden used.

2/6+3/12= 5/12

Now subtract 12/12(the whole garden) from 5/12 to get remainder of garden

Answer is: 7/12
