Answer:
The one you are or were about to pick is correct.
Step-by-step explanation:
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9
Answer:
to do this question, add width + height. 4/6 + 2/5 are not normally add-able. So to correct this, we find the most common factors. There is 1, 5, and 6 at highest. 5 and 6 share a high number multiple if you combine them. This multiple is 30. So now, keep, change, flip.
4x2 is 8.
6x5 is 30.
I would say the answer should be eight thirtieths.
