Lets answer this:- 1st lets divide to see how many times 28 goes in 8. And then we will multiply.... 28 ÷ 8 = 3.5 Now lets multiply to see how many symphonies are equal to 25 concerts. Lets do it:- 3.5 × 6 = 21 So, 21 symphonies are equal to 28 concerts.  Lets divide to see how many concerts are equal to 42 symphonies and the multiply to get our final answer.  42 ÷ 6 = 7 7 × 8 = 56. So, 56 concerts are equal to 42 symphonies. Hope I helped ya!!

8 : 6  Now, we need to solve for the proportion. 8/6 = 28/x Cross multiply. 8*x = 8x 6*28 = 168 8x = 168 8x/8 = 168/8 x= 168/8 x= 21 For 28 concerts, there are 21 symphonies.  Now, set up another proportion. 8/6 = x/42 Cross multiply 8*42 = 6x 6x= 336 6x/6 = 336/6 x= 336/6 x= 56 For 42 symphonies, there are 56 concerts.
