Use ratios to move faster on the SAT

Use ratios to move faster on the SAT

I did that in my head in legit a couple of seconds

Have any of the common core kids taken the SAT’s yet?

[cannonballjenkins]

theres a super simpler way of doing this but sure, maybe a couple hours isn't long enough for some people and you want to speedrun I guess

[hapax-sifd]

Yeah then for some reason i put the wrong answer. I either flubbed the simple multiplication or went dyslexic when circling the answer, but i see these and know how to do them just as he did, think this is easy i got this boom wrong lol

Maybe it’s easy but I’m trying to follow his logic. If anyone can talk more about this if your not solving for x by subtracting and dividing first you just multiply 12 by 4 how do you know you are coming up with the correct solution. Where is the actual ratio you use?

i don't why you are solving basic question i have doubt that you are just lying us because that u can't solve difficult question
