<h3>
6/11 = y/3</h3>
<em>Multiply both sides by 3.</em>
<h3>6/11 × 3 = y</h3>
<em>Express 6/11 × 3 as a single fraction.</em>
<h3>6 × 3/ 11 = y</h3>
<em>Multiply 6 and 3 to get 18.</em>
<h3>18/11 = y</h3>
<em>Swap the sides so that all the terms of the variables are on the left side.</em>
<h3>y = 18/11</h3>
GCF(18,36) =
GCF(36,18) =
GCF(18,0) =
18
Explanation:
There is a rule that: 'the GCF of two numbers a and b is the same as the GCF of b and a%b'
a%b means the remainder after doing a/b
Area = 1/2 * ( sum of 2 parallel sides) * height
= 1/2 * (7 + 10) * 7
