6 / (1 - 5/7)
The answer is 6 / (1-5/7). 1- 5/7 = 2/7 6 / (2/7) = 6 * (7/2) = (6*7)/2 = 42/2 = 21. Simples!
9 + 5 + 3 + 3 + 1 + 1 = 21
For this particular problem, you just need to experiment a little. 1 + 2 + 3 + 4 + 5 +6 = 21 (6 integers).
126.... without using a calculator !
6 / (1 - 5/7)
It can be: (5*6)-21 = 28
How do you add 9, 5, 3, and 1 in such a way to get sum of 21 by using only 6 numbers?You would add 9+5+3+1+1+2 and your answer would be 21.
3*5=15+3+3=21
6+5+5+5
(9+5+5+1+1) x 1
I'm not sure if you are limited by purely addition or what the rules are so I have the following answer:Using only 6 numbers, but any function:3*5-5+9+1+1 = 21
3*3*3-(5+(5/5)) 9+3+3+5+1(to the power of 1) ...using 6 numbers logic fullfilled ...here in this answer v use the clause of using all given digits
The answer is 6 / (1-5/7). 1- 5/7 = 2/7 6 / (2/7) = 6 * (7/2) = (6*7)/2 = 42/2 = 21. Simples!
7-6=1, 1+5=6. 6 is your answer.
5*(7*3 - 6) = 5*(21 - 6) = 5*15 = 75
7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.7/10 - 1/6 = 21/30 - 5/30 = 16/30 = 8/15.
