Answer:
She increased 80% the practise time
Step-by-step explanation:
The question is incomplete, the following is missing:
<em>by how much did she increase the time she practised each day?
</em>
From Monday to Wednesday she increased 90 - 50 = 40 minutes the practise time.
To compute the increment as a percentage use: increment/reference *100
In this case, that is: 40/50*100 = 80%, where 50 minutes is taken as a reference.
Answer:
11/24
Step-by-step explanation:
7/8 + 11/12 + 3/4 + x = 3 km
7*3/8*3 = 21 / 24
11*2 / 12 * 2 = 22 /24
3*6 / 4*6 = 18/24
21/24 + 22/24 + 18/24 + x = 3
61 / 24 + x = 3
x = 72/24 - 61/24
x = 11 / 24
