Select the following statement that is true about shape a and shape b. Question 12 options: Similar—shape b has been stretched,
but all its angles have the same measure, so these shapes must be similar. Similar—shape b has been dilated, so the shapes are similar but not congruent. Not similar—shape b has been stretched, these shapes are neither similar nor congruent. Not similar—though you can obtain shape a from shape b, you cannot obtain shape b from shape a.

Answer:
Step-by-step explanation:
First, we need to find the common denominator
The easiest way to do this is by multiplying the two given denominators, which are 2 and 5.
2 × 5 = 10
So, our common denominator is 10. Then, multiply the numerators of the two fractions by 2 and 5. Here's why:
=
We multiplied the top and bottom by 2 to make sure our new fraction stays equivalent to the original fraction.
Do the same thing for the other one:
=
Finally, subtract the two fractions to find the difference between the two times:
=
The reason we used the common denominator is because we can only add or subtract fractions if they have the same denominator.
