12 ÷ 3= 4. Hope this helps. ;)
Okay first I think you might’ve highlighted incorrectly. You want to make sure the angles match with each other. Next you set up a proportion and solve. I’ll draw this all out for you. I hope this helps! :))
1. -.6 or -3/5
2. -.4 or -4/9
The answer is 54, 5 is 1 more than 4, they equal 9, 54 is 6 times greater than 9
