Answer:

9/5

Explanation:

original fraction : x/y

new fraction = .9x/(.5y)

= 9x/5y

(9x/5y) / (x/y)

= 9x/5y * y/x

= 9/5

= 1.8

so it increased by 80%

e.g suppose we had 100/200 or 1/2

new fraction = 90/100 or 9/10

new ratio = (9/10) / (1/2)

= 9/5

Suppose that we have a fraction. Let use 10/10 for example. Let do the transformation and see what happens to the fraction.

10/10 ----> 9/3

The number changed from 1 (10/10) to 3 (9/3).

The fraction increases by 200%.

IRISSAK [1]

The product of expressions or numbers is calculated by multiplying the expressions or numbers.

  • The incorrect value in the table is -2y
  • The value that should have been written is -2xy

From the table (see attachment), the incorrect product is given as:

-y \times 2x = -2y

The above product is incorrect.

This is so because when -y is multiplied by 2x, the result is -2xy

So, the correct expression is:

-y \times 2x = -2xy

All of the following are good reasons to attend postsecondary institutions except:
Ksivusya [100]

The best answer to the question would be (A) longer average life span.

Though there is a correlation between life span and education levels, where the higher your education, the higher your life span, other factors influence how long you life, most notably, of course your fitness levels, health, and diet. Thus, if you want to live longer, it is better to invest your time and effort into those three things instead of attending a postsecondary institution.
