Walter practices piano for 1/4 hour 1/2 hour or 3/4 hour every other day. If a lion plot shows two Xs above each value of time, what is the total amount of time Walter has spent practicing

the total time walter spent practicing is 3 hours

Step-by-step explanation:

If a lion plot shows two Xs above each value of time, this means that 2 times he did a practice of that time

so to know the total time we would have to add up all the practices he did for each time

2 * 1/4 h + 2 * 1/2 h = 2 * 3/4 h =

2/4 h + 2/2 h + 6/4 h =

1/2 h + 1h + 1 1/2 h =

1/2 h + 1/2 h + 1h + 1h =

1h + 2h = 3h

the total time walter spent practicing is 3 hours
