Please help 3/5 + 5/10

1.1 or 11/10

Step-by-step explanation:

We can "lengthen" 3/5 by multiplying both the top and bottom number with 2.

It'll still be the same fraction, but we'll get 10 at the bottom.

This gives us 10 at the bottom, which means we can now add it to 5/10.

1.1 or 11/10

where is the picture

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.
