Question

There are 40 students at bail high who plat stringed instruments of these 1/4 play viola 1/5 play cello and the rest play violin how many students play violin

Answer 1

Answer:

I'm not to sure but I think it's 39 11/20

Step-by-step explanation:

1/5 + 1/4 you have to get a common denominator which would be 20 and then you add the numerators to get 9. Then you would subtract 40 from 9/20 and have to get the common denominator again which would be 800/20 - 9/20 which is 751/20 simplified to 39 55/100 simplified even more to 39 11/20. I haven't done fractions for a while so it might be wrong. I hope I helped!
