Question

Propon

Answer 1

Answer:

They are shown together to find units of 4 total

4 (j/ total + s/total )

= 4 (1/4 + 3/4)

=  4/4 + 12/4

= 4 cups total

Then show letters and work out for j + s

4(j/3 + 3/4) = 4

4j/3 + 12/4 = 4

4j/3 + 3 = 4

4j/3 = 4-3

4j/3= 1

j = 1/3     s = 3/4 * 4 = 3  

You would rearrange 4 within the brackets to find total

3 (1/3 + 4t) = 4

   1 + 12t = 4

         12t = 4-1

         12t = 3

             t = 12/3 of the total

            t = 4
