Ok so it's a proportion so this fraction is to this fraction. the smaller rectangle has sides 4 and 12. the larger one has 8 and x. so u set it up 4/12=8/x. the 4 and 8 r both the short sides so u want those on top and 12 and x r long sides so those on bottom. since that is not an answer option u can set it up as 8/4=x/12 because u still keep the variables of the same rectangle from being multipled with each other. so answer #2 is correct

Please help me with this. simplify and show all your work.

Let's take this variable by variable. z to the power of 4 over z to the power of one would equal z to the power of 3. At this point, there is no longer a z variable in the denominator.
X to the power of 2 over x to the power of 1 would equal x. At this point there is also no x variable in the denominator.
Y to the power of 1 over y to the power of 2 would equal (1/y). At this point, there is no y in the NUMERATOR. 

Final Answer: \frac{ z^{3}x }{y}

taurus [48]

Answer:

5/4

Step-by-step explanation:

The slope intercept form for a linear equation is y = mx + b. The variable's (x) coefficient, which is represented as m, is the slope of any linear equation.

What's the largest fraction in eaxh group? a. 5/6 and 29/36 b. 5/12 and 3/8 c.2/5 and 19/45 d.5/7, 13/14, and 19/21
Sever21 [200]

Answer:

a) \frac{5}{6}is greatest fraction.

b) \frac{5}{12} is greatest fraction.

c) \frac{19}{45} is greatest fraction.

d) \frac{13}{14} is greatest fraction.

Solution:

To compare two fraction we need to make denominator of both the fraction same.

a)Given fraction are \frac{5}{6} and \frac{29}{36}

\frac{5}{6}=\frac{5 \times 6}{6 \times 6}=\frac{30}{36}

So \frac{30}{36} is equivalent to \frac{5}{6}

So \frac{30}{36}>\frac{5}{6}

Hence \frac{30}{36} that is \frac{5}{6} is greater than \frac{29}{36}

b)Given fraction are \frac{5}{12} and \frac{3}{8}

\frac{5}{12}=\frac{5 \times 2}{12 \times 2}=\frac{10}{24}

Similarly we get \frac{3}{8}=\frac{3 \times 3}{8 \times 3}=\frac{9}{24}

So \frac{10}{24}>\frac{9}{24}

\frac{10}{24}>\frac{9}{24}

That is \frac{5}{12}>\frac{3}{8}

Hence \frac{5}{12} is greater than \frac{3}{8}

c) Given fraction are \frac{2}{5} and \frac{19}{45}

\frac{2}{5}=\frac{2 \times 9}{5 \times 9}=\frac{18}{45}

So \frac{19}{45}>\frac{18}{45}

That is \frac{19}{45}>\frac{2}{5}

Hence \frac{19}{45} is greater than \frac{2}{5}

d)Given fraction are \frac{5}{7}, \frac{13}{14} and \frac{19}{21}

\frac{5}{7}=\frac{5 \times 6}{7 \times 6}=\frac{30}{42}

\frac{13}{14}=\frac{13 \times 3}{14 \times 3}=\frac{39}{42}

Similarly we get  

\frac{19}{21}=\frac{19 \times 2}{21 \times 2}=\frac{38}{42}

So \frac{39}{42}>\frac{38}{42}>\frac{30}{42}

That is \frac{13}{14}>\frac{19}{21}>\frac{5}{7}

Hence \frac{13}{14} is greatest fraction.
