• So... Is it just me or I don't get this at all. :/
• I can't get this either.
• I still don't get how 6x0.25 is 1.5
• When you think about it, 0.25 is the same as 1/4, just as a different form. So if you multiply it the fraction way : 6/1 x 1/4, we get 6/4. As a decimal, 6/4 is the same as 1.5

If I'm confused about these type of questions, I use this method. So I hope you find this helpful!
• can we replay the video?
• Yes you can. Their is a replay button on the bottom left corner of the video screen.
• These are linear equations, which has a to do with the coordinate plane, KA's Get Ready for Geometry course has a unit that that could help you understand this better if you or anyone else are still wondering.
• when you think about 0.50 is it the same as 2/4
• it is the same as 2/4
• how are u suppose to pronounce the e that has the 2 dots on the top
• i dont get this at all
• 15 = 3.75.
This is a bit confusing but I noticed. every proportional relationship needs to have the same divided number which in this case, is 4. Now use a calculator to test these problems. (I hope what I'm saying makes sense
• I divide
12 / 3=4
6 / 1.5 =4
3 / .75=4
