j=4.88 when g=8 and v=11
Further explanation:
When the increase/decrease in one quantity cause increase/decrease in other quantity, it is called direct variation.
Variation is always accompanied by a variation constant.
<u>Given</u>
g and v vary directly with j
IT can be written as:
j∝gv
Putting the variation constant k
j = kgv
Putting g = 6 and v=3
So the value of k is 1/18 which makes the equation
So, j=4.88 when g=8 and v=11

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 .
