Which fraction expresses 36/80 in lowest terms? Please help me ;D
JulijaS [17]
To reduce<span> a </span>fraction to lowest terms<span> (also called its simplest form), divide both the numerator and denominator by the GCD. For example, 2/3 is in </span>lowest<span> form, but 4/6 is not in </span>lowest<span> form (the GCD of 4 and 6 is 2) and 4/6 can be expressed as 2/3.

38/80= 19/40

I need help on this question I’m confused I think a &amp;b are the same and c &amp;d are different but I’m not to sure !
Nina [5.8K]
<h3>Answer:  They're all the same</h3>

====================================================

Reason:

2^6 means we have 6 copies of "2" multiplied out as shown in choice B. That explains how A and B are the same, and we can say

2^6 = (2*2*2)*(2*2*2)

The parenthesis are optional, but I find they're handy to count the '2's easier.

----------------

Now notice that

2^3 = 2*2*2

So,

2^6 = (2*2*2)*(2*2*2)\\\\2^6 = (2^3)*(2^3)\\\\2^6 = (2^3)^2\\\\

The last step is possible because we have two copies of 2^3 multiplied together.

This shows that choice C is equivalent to A and B.

-------------------

Lastly,

2^6 = (2*2*2)*(2*2*2)\\\\2^6 = (2*2)*(2*2)*(2*2)\\\\2^6 = (2^2)*(2^2)*(2^2)\\\\2^6 = (2^2)^3\\\\

The jump to the last step is possible because we have three copies of 2^2 multiplied together.

This shows choice D is equivalent to the others.

All four expressions are the same.

They represent different ways to say the same number. That number being 64.
