Multiply the fraction top and bottom by 25 so the denominator is 100 (how many cents are in a dollar):
[tex] \frac{75}{100} [/tex]
Since there are 100 cents in a dollar, so the stamp costs:
[tex] \frac{44}{100} [/tex]
To convert both of these fractions into decimals, write the top number and move the decimal place one space to the left for each zero in the bottom number (100 = 2 zeros, move decimal two places).
Elise had 0.75 cents and spent 0.44 cents on the stamp. She now has 0.33 cents left.
Given:
Question:
The Process:
Step-1: Prepare [tex]\frac{3}{4}[/tex] to be decimal
Both the numerator and denominator are multiplied by 25.
[tex]\boxed{ \ = \frac{3}{4} \times \frac{25}{25} \ }[/tex]
[tex]\boxed{ \ = \frac{75}{100} \ }[/tex]
[tex]\boxed{\boxed{ \ 0.75 \ }}[/tex]
Step-2: Find out about Elise's money at first
[tex]\boxed{ \ = \frac{3}{4} \times \$ 1 \ }[/tex]
[tex]\boxed{ \ = 0.75 \times \$ 1 \ }[/tex]
Thus before she buys a stamp, she has [tex]\boxed{\boxed{ \ \$ 0.75 \ }}[/tex]
Step-3: Elise buys a stamp that costs 44 cents
Let us convert 44 cents into dollars.
Recall that [tex]\boxed{ \ \$ 1 = 100 \ cents \ }[/tex]
[tex]\boxed{ \ = 44 \ cents \times \frac{\$ 1}{100 \ cents} \ }[/tex]
We crossed out the cent unit.
[tex]\boxed{ \ = \$ \frac{44}{100} \ }[/tex]
Thus she buys a stamp that costs [tex]\boxed{\boxed{ \ \$ 0.44 \ }}[/tex]
Step-4: How much money Elise has after paying for the stamp
To obtain Elise's remaining money, the initial amount of money subtracted by the cost of a stamp.
[tex]\boxed{ \ = \$ 0.75 - \$ 0.44 \ }[/tex]
Thus Elise's money left after paying the stamp is [tex]\boxed{\boxed{ \ \$ 0.31 \ }}[/tex]
