63-13 = 50
13% of 63 is 8.19
The answer is 63. This is because 5 tens = 50 and 13 ones is 13. Then, add 50 and 13, and you get 63.
To find the percentage of one number in relation to another number then divide the relative number (in this case 13) by the base number (in this case 63) and multiply the result by 100.13 as a percentage of 63 = 100 x 13/63 = 20.635% (3dp)
39 / 3 = 13 63 / 3 = 21
It is: 63/91 = 9/13
63/117 = 7/13
No.
The factors of 13 are: 1, 13 The factors of 21 are: 1, 3, 7, 21 The factors of 63 are: 1, 3, 7, 9, 21, 63 because these are the positive integers that divide evenly into 63 with no remainder. The factors of 79 are: 1, 79
The sum of 54 and 63 is 117. This can be expressed as the product of 9 and 13, where 9 and 13 are relatively prime addends. Therefore, 54 + 63 = 9 × 13.
The greatest common factor would be 1. Since 63 is not divisable by 13.
