Question

Angely spent $22 of the $40 she got for her birthday. Which decimal represents the fraction of the $40 Angely did NOT spend?

Option 1: 0.55
Option 2: 0.45
Option 3: 0.75
Option 4: 0.25

Answer 1

Angely did not spend $18 of her $40. Dividing 18 by 40 gives us 0.45, so the correct decimal representation of the fraction she didn't spend is 0.45.

Step-by-step explanation:

The question asks which decimal represents the fraction of the $40 Angely did NOT spend after spending $22 of her birthday money. To find out what fraction she did not spend, we need to subtract the amount spent from the total amount. So, $40 - $22 equals $18. The fraction of the $40 that she did not spend is thus 18/40. To convert this into a decimal, we can simplify the fraction to 9/20 and then divide 9 by 20 which equals 0.45.

Now we can look at the options provided:

• Option 1: 0.55
• Option 2: 0.45
• Option 3: 0.75
• Option 4: 0.25

As we calculated, option 2, which is 0.45, is the correct decimal representation of the fraction of the $40 that Angely did not spend.
