Answer 1

Austin spent 85 cents on an eraser and a pencil; this is equivalent to 85/100 of a dollar, or 0.85 when expressed as a decimal.

Step-by-step explanation:

Austin bought an eraser for 65 cents and a pencil for 20 cents. To find out what fraction of a dollar he spent, we first need to add the cost of the eraser and the pencil together: 65 cents + 20 cents = 85 cents. Since there are 100 cents in a dollar, Austin spent 85 out of 100 cents, which can be written as the fraction 85/100.

When converting this fraction to a decimal, we simply divide the numerator by the denominator. Therefore:

In words, X = 85 cents / 100 cents

X~ = 0.85

So, Austin spent 0.85 of a dollar on the eraser and the pencil.

Answer 2

Eraser cost = 65 cents

Pencil cost = 20 cents

Total cost = 65 + 20

= 85 cents

85 cents to $1 (i.e. 100 cents) as a fraction written as:

`\begin{gathered} (85)/(100) \\ 0.85 \end{gathered}`

Final answer:

85 cents to a dollar is $0.85
