answer: Riley practiced soccer for 2 1/4 hours Monday and Tuesday. she practiced 2/4 more hours on Wednesday than Tuesday.
Step-by-step explanation: 1/2 is essentially 2/4, add 3/4 it becomes 1 1/4 now add one for 2 1/4.
this is quite self explanatory. 1 1/4 - 3/4 is step by step like this. 1 1/4 - 1/4= 1.
1- 2/4 (half of one whole.) = 2/4.
I hope that explains it.
