Which of the following is an example of a proper fraction? A. 4 /3 B. 4 /4 C. 3 /4 D. 7 /6
puteri [66]
<span>The proper fraction is c. 3/4. A proper fraction is a fraction that is less than one. A fraction is less than one if its denominator, the number below the line, is larger than its numerator, the number above the line. 4/3 and 7/6 are both greater than one and 4/4 is equal to one, thus none of them are proper fractions.t</span>

You are making several purchases from the b-better electronics store. You can buy from this store online or in a physical store.
alexandr402 [8]

Answer:

Online Ordering is better.

Step-by-step explanation:

So you now that you save 20% if you to physical store and you save $20 if you go to the online store.

Say you are spending 100 dollars at the store to make it easy. 20% of one hundred is $20 so that is the same amount of money.

Now let’s look at the taxes and shipping so at the physical store you have to pay taxes no matter what but online you only do it if you purchase is less than $75 and we have $80 ($100–$20=$80) so at the physical store you have some amount of Mandy that is more than $80 because of taxes but if you buy online it will be exactly $80.
