Difference means minus the two numbers
ie. 29 - 14 = 15
This means that the difference is 15.
14
-29.
It is: 29*14 = 406
14 out of 29 = 48.3%
There are 14 protons in 29Si. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying silicon-29) is unneeded.
the sum of -14 + 29 is 15
14/29 cannot be simplified
29
14 goes into 29 twice with a remainder of 1. 29/14 = 2 r 1 or approximately 2.07.
To find four times the difference between 57 and 29, first calculate the difference: 57 - 29 = 28. Then, multiply that difference by four: 4 × 28 = 112. So, four times the difference between 57 and 29 is 112.
The Least Common Multiple of 14 and 29 is 406.
