.

Step-by-step explanation:

Given:

Tina cut 3 wood boards each into 4 equal pieces.

She used 3 of the pieces for a craft.

Question asked:

What fraction of the boards does she have left ?

Write this fraction as a mixed number.

Solution:

As she cuts 3 wood board each into 4 equal pieces :-

Total number of equal pieces =

Pieces of wood used = 3

Remaining pieces = 12 - 3 = 9

By unitary method:

4 pieces constitute = 1 wood board

1 piece constitute =

9  pieces constitute =

Now, convert it into mixed fraction:

Therefore, fraction of the boards she have left is .

9 x 8 divided by (5-3)=36
