So the number of integers divisible by 7 in the given range is 100/7 = 14 (and a fraction that we don't care about). \n" ); document.write( "The numbers in the given range that are divisible by both 7 and 6 are the multiples of 7*6 = 42. In the given range, there are 3 such numbers: 42, 84, and 126. \n" ); document.write( "So the number of integers in the given range that are divisible by 7 but not by 6 is 14-3 = 11. \n" ); document.write( "ANSWER: 11 \n" ); document.write( " \n" ); document.write( " |
