Answer:
.
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:
<em><u>As she cuts 3 wood board each into 4 equal pieces :-</u></em>
Total number of equal pieces =
Pieces of wood used = 3
Remaining pieces = 12 - 3 = 9
<h3><u><em>Now, we will write these 9 pieces in terms of number of wood boards</em></u>.</h3><u>By unitary method:</u>
4 pieces constitute = 1 wood board
1 piece constitute =
9 pieces constitute =
<em>Now, convert it into mixed fraction:</em>
Therefore, fraction of the boards she have left is .
