If you want 7 times 3 then it is 21 but if you want 7 times 313 then it is 2191 and if you want 7 times 3 times 13 that is 273
7 divided by 13 times 2 divided by 3 is 14/39
7 times with 13 remaining
3 1/4 * 3 5/7 = 13/4 * 26/7 = 13/2 * 13/7 = 169/14 = 12 1/14
To convert the number ( (6 , 13)_7 ) into standard form, first note that it is in base 7. The number can be expressed as ( 6 \times 7^1 + 13 \times 7^0 ). Since ( 13 ) is not a valid digit in base 7 (valid digits are 0-6), it seems there might be a misunderstanding. If you meant ( (6 , 1 , 3)_7 ), then it would equal ( 6 \times 7^2 + 1 \times 7^1 + 3 \times 7^0 = 6 \times 49 + 1 \times 7 + 3 = 294 + 7 + 3 = 304 ) in decimal (standard) form.
It is -386.

y*49/39 = 7/13 => y = 3/7
91 divided by 13 = 7 13 can go into 91 7 times
1. 7(3) - 2 · 4 13 21-8 21-8=13 Since this is pre- algebra I do realize that you mean. The answer is 13 :D
(3/7)(10/13)(14/15)=(4/13).
7 * 11 * 13 * 6 = 6,006
