Step-by-step explanation:
1:0.8 is 5:4. 16 is the 4 and so the 5 is 4(1)x5 = 20.
If you would like to know how much is 68% of 12, you can calculate this using the following steps:
68% of 12 = 68/100 * 12 = 816/100 = 8.16
Result: 68% of 12 is 8.16.
Step-by-step explanation:
=> x + 80 + 20 = 180
=> x + 100 = 180
=> x = 180 - 100
=> x = 80°
