Timmy used to practice the violin for 60 minutes everyday. Now, he practices 135% as many minutes as he used to. How many minutes does he currently practice everyday?

81

Step-by-step explanation:

You need to work out 35% and add it to 100% to make 135%

To do that you work out 10% and multiply it by 3 to give you 30%. After that you need to work out 5% and add it to the 30%. You can work out 5 %by dividing the answer you get for 10%

100%=60 minutes

10%=6

30%=18

5%=3

35%=21

60+21=81 minutes
