Answer:
Theo practices yoga on Saturday 57 more minutes.
Explanation:
With the information provided, you can find the total amount of minutes Theo practices yoga that would represent 100% using a rule of three considering that you know that 24% of his daily yoga practice is equal to 18 minutes:
24% → 18
100% → x
x=(100*18)/24=75
As you need to find how many more minutes does Theo practice yoga on Saturday, you have to subtract 18 minutes that is the amount he has already spent practicing yoga from 75 that is the total amount of minutes he practices yoga:
75-18=57
According to this, Theo practices yoga on Saturday 57 more minutes.
