6.3
It is because... well lets work the problem and see what happens. 63 divided by 0.1 is 63 divided by 1/10. 63 divided by 1/10 is 63 multiplied by 10/1, or 10 63 x 10 is 630. Lets check if its correct. 630 x0.1 ------ 63.0 I hope it makes you understand.
63 / 10 = 6.3
The answer is 55. By order of operations, this is: sqrt(64)/sqrt(16) + [(3)2 x 7] - 10 = 8/4 + 63 - 10 = 65 - 10
63/10 + 100 = 106.3
28 divided by 7 is 4. SO 63 minus 4 = 59
10 minus 3 and 2/5 = 7 minus 2/5 = 63/5
7 times 9 is 63 63 divided by 9 is 7 63 divided by 7 is 9
