marty has saved $72. he spent $8 on a video rental. write a ratio as a fraction in simplest form to represent what portion of his savings he has left

Answer 1

To find what portion of Marty's savings he has left, subtract the amount he spent from his total savings:

$72 - $8 = $64

Therefore, Marty has $64 of his savings left.

To represent this as a ratio in simplest form, we can write:

$64 / $72

This can be simplified by dividing both the numerator and denominator by 8:

$8 / $9

So, the ratio in simplest form representing what portion of his savings Marty has left is 8/9.
