You move the decimal how ever many times it takes to make it a whole number, but you have to do the same to the other number even if the other number doesn't have a decimal in it. For example 6.78 divided by 45. You would move the decimal spot twice to make 6.78 into 678. Then you have to move the "decimal place" in 45. This will then make it 4500

Sam practices his guitar for 9 hours each week he practices each song for 3 1/2 hours. What is the greatest number of song he ca

liberstina [14]

Answer:

<em>The greatest number of song he can practice in a week is 2.</em>

Step-by-step explanation:

Suppose, the greatest number of song he can practice in a week is $x$

He practices each song for $3\frac{1}{2}$ hours. So, the total time required for practicing $x$ number of songs $= (3\frac{1}{2}*x)$ hours.

Given that, he practices his guitar for 9 hours each week.

So, the equation will be......

$3\frac{1}{2}*x= 9\\ \\ x= 9\div 3\frac{1}{2}\\ \\ x=9\div \frac{7}{2}=9 \times \frac{2}{7}=\frac{18}{7}= 2.571.... \approx 2$

<em>(Rounded as the greatest whole number)</em>

Thus, the greatest number of song he can practice in a week is 2.

Dianne purchased a ham for $45.15. How many pounds is the ham if it sells for $6.45 per pound?

Len [333]

It would be 7lbs, you divide the total amount by the amount per pound and you get the weight.
