Multiply the denominators together.

(8)(7)=56

2/56 - reduce

divide by 2 for the numerator and denominator

2/2=1

56/2=28

Answer:

<u>1/28</u>

Step-by-step explanation:

Alrighty, so you start off with 2/8 x 1/7, you just have to multiply across (2x1 (numerator) and 8x7 (denominator) and you will get 2/56.

Now, you have to simplify this fraction. The number 2 goes into both the numerator and denominator, so, divide 2 by 2 (1) and 56 divided by 2 (28).

Your answer should be 1/28.

Hope this helps! ^-^

Robert ran 3 1/3 mph for 3/4 of an hour. How far did he run?​
matrenka [14]

Answer:

2 ½ miles

Explanation:

mph = miles per hour, which means that if robert had run for the full 1 hour, he would have run 3 ⅓ miles.

however, since he only ran for ¾ of an hour, which is equal to 0.75, we can multiply the 3 ⅓ miles by 0.75 to get 2.5 or 2 ½ miles.

i hope this helps! :D

Which transformation is not always congruent with its original image
Anika [276]

If they're asking for "congruent" which we know is the shape is the same or equal to. Out of the transformations I assume Dilation because you're altering the size of the shape meaning the image is either bigger than or less than the pre-image. Of course a shape bigger is not equal to the original shape.

think of a king size candy bar to a fun size bar. they're not congruent or the same
