Step-by-step explanation:
Collinear points have the same gradient
find the gradient(slope) between AB first

Find the one for BC

Find the gradient between AC now

YOUR LAST STATEMENT NOW WILL BE
POINTS A,B AND C ARE COLLINEAR SINCE THE GRADIENTS BETWEEN THEM IS THE SAME!!!
4:3 8:6 24:18 20:15 is the complete ratio table.
Step-by-step explanation:
I am not critically certain but the ways you have jotted down your enquiry..
<h2>I assume is</h2>
13 × (4×11)
13 × 44
=572 - 44= 528
528+13 =541
541 ×13=7033
