Turn it into a fraction 8/20 then you can lower it to 2/5 because four goes into eight twice and into twenty five times. Once you have done that it is easy to figure out that 2/5 is 40%
Your answer will be 8+35×5=215 because she works out 43 minutes total a day (8+35=43) and then you have to do that for 5 more more day so you can do 43 × 5 or 43+43+43+43+43 your answer will come out the same
