Answer:

The answer is 14z

Step-by-step explanation:

25z - 8z + (-3z)

-8z + (-3z) is the same thing as -8z - 3z, which equals -11z,

25z - 11z = 14z

3 3/8 divided by 3/4 using cross multiplication algorithm
Bogdan [553]

Answer

3 3/8 ÷ (3/4) = (9/2) = 4 ½

Explanation

We are asked to evaluate 3 3/8 divided by 3/4 using cross multiplication algorithm.

The algorithm will need us to put the mixed fraction in definite fraction form (improper fraction) and to evaluate the division, we change the division sign into multiplication sign and the fraction after the division sign changes into its reciprocal.

3 3/8 = (27/8)

(3 3/8) ÷ (3/4)

= (27/8) ÷ (3/4)

\begin{gathered} \frac{27}{8}\div\frac{3}{4} \\ =\frac{27}{8}\times\frac{4}{3} \\ =\frac{108}{24} \\ \text{Divide numerator and denominator by 12} \\ \frac{108}{24}=\frac{9}{2} \end{gathered}

Hope this Helps!!!

Find the LMC of 12 and 30
dlinn [17]

Answer:

60.

Step-by-step explanation:

I guess you mean the LCM (Lowest Common Multiple):

12 = 2 * 2 * 3

30 = 2 * 3 * 5

We see there are duplicate 2's and 3's so:

So the LCM  is 2 * 2 * 3 * 5 =  60.

(the duplicates only appear once in the calculation).
