1.625 as a fraction is 1 5/8

15/8 simplified is 1 7/8

if you are using the word "and" to represent multiplication here you go:

first i would change both fractions to a mixed number

13/8×15/8=195/64
simplify

your answer would be 3 3/64

if you are using "and" to represent adding here you go:

1.625 as a fraction is 1 5/8

first i would change 1 5/8 to a mixed number: 13/8

so then add 15/8+13/8=28/8

simplify:
28÷4=7
8÷4=2

7/2=3 1/2

Simplify the following : x^2y^-3 / x^5y^2

Likurg_2 [28]

Answer:

Step-by-step explanation:

$\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}$
