Answer:
57
Step-by-step explanation:
We need to create a ratio. so Aubree practices the piano for 1197 min: in 3 weeks. So for 1 week, we have to divide 1197 by 3, so 1197/=399. And so we know that 1 week is 7 days, just divide 399 by 7! 399/7=57. The rate that she practiced per day is 57 minutes. So one last final step just to check if this answer is correct is to divide 57 by 60, and that is 0.95. 0.95 out of 1.00 minutes per day is 95/100. Cross multiply with x/60, and you will get your answer, which is 57.

The difference between the two mass is 151950g
Data;
- Mass a = 29.48kg
- Mass b = 181,430g
<h3>Difference Between The Mass</h3>
To calculate the difference between the mass, we must do so in the same unit. i.e both mass a and mass b must be in the same unit.
<h3>Conversion of Mass from Kg to g</h3>
Let's convert mass a from kg to g

Using this, we can find how many grammes are in 29.48kg

Now we can find the difference between mass b and mass a

The difference between the two mass is 151950g
