What is the difference in length between a 1 in a half 1/4 inch button and a 3/8 button?

1 1/4= 1 2/8  1 2/8-3/8= 7/8 hope this helps

Step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

150
