M = 4
Because the base of log is 10
10,000 is 10*4, and we know that log 10,000 =4, so M=4
11 to 25, because if your counting 11 and there's 25 in all, then 11 to 25
First you can simply this fraction to make it a little easier:
650/250 = 65/25 = 12/5
Now you divide:
12/5 = 2.4
and multiply this result by 100%:
2.4 * 100% = 240%
12 is 240% of 5.
Deep because it has a line above the 4
