List multiples to find LMC of 27 and 45
PtichkaEL [24]

Answer:

135

Step-by-step explanation:

I think you mean the LCM instead of LMC. LCM stands for Least Common Multiple. Anyway, some of the multiples of 27 are 27, 54, 81, 108, and 135. Some multiples for 45 are 45, 90, 135. We can see here that 27 and 45 share the mutiple of 135 which is the first number they have in common.

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.
