It is: 140+70 = 210
Oh, dude, the ratio of 210 to 140 is like 3:2. It's just a fancy way of saying if you have 210 things, you'd have 3 times as many as if you had 140 things. But like, who's counting, right?
It is: 840
4 over 144 simplified = 1 over 36
It is already simplified.
168/210 = 4/5
70
No.
Yes, it can.
It is: 77/140 = 11/20
27/70
3/140
It is: 3/5
77/140 = 11/20 simplified
Oh honey, of course it can be simplified. Just divide the top and bottom by their greatest common factor, which is 6 in this case. So, 210 divided by 6 is 35, and 36 divided by 6 is 6. Voila! 210 over 36 simplified is 35 over 6.
2/3
The Greatest Common Factor (GCF) of 210 and 140 is 70.
