To find the ratio of what portion of his savings Marty has left, we need to subtract the amount he spent from his total savings and then express it as a fraction in simplest form.
Marty's savings: $72
Amount spent: $8
To find what portion of his saving he has left, we subtract the amount spent from his total savings:
$72 - $8 = $64
Now, let's express this difference as a fraction in simplest form:
The portion of his savings remaining is $64.
To represent this as a ratio, we can write it as:
64/72
To simplify this fraction to its simplest form, we can divide both the numerator (64) and the denominator (72) by their greatest common divisor, which is 8:
64/72 = (64 ÷ 8) / (72 ÷ 8) = 8/9
Therefore, the ratio of what portion of his savings Marty has left is 8/9.
