To find a percentage of a number, you just need to multiply the percentage by that number.
Percentages must be converted into decimal form before any work can take place. We can do that by either dividing the percentage by 100, or (my personal shortcut) by just shifting the decimal point to the left two places.
276% = 2.76
Then, we just need to multiply.
2.76 * 8 = 22.08
Since the question requires the answer in fraction form, we need to convert 22.08 to a mixed number. This mixed number would be 22 2/25
276% of 8 in fraction form is 22 and 2/25.
Hope this helped =)
Answers:
- Zainab made more money
- She made $2.50 more
=======================================================
Explanation:
To find the hourly rate, we divide the money made over the number of hours.
- Zainab's hourly rate = 44/8 = $5.50 per hour
- Keziah's hourly rate = 47.25/9 = $5.25 per hour
Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours
- Zainab: 5.50*10 = 55 dollars
- Keziah: 5.25*10 = 52.50 dollars
We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.
Answer:
114
Step-by-step explanation:
To find - Find the sum of all the two-digit numbers that divide 170 with a remainder of 5.
Proof -
The 2 digit number is 11
170 = 11(15) + 5
The two digit number is 15
170 = 15(11) + 5
The two digit number is 33
170 = 33(5) + 5
The two digit number is 55
170 = 55(3) + 5
∴ we get
The two digit numbers are
11, 15, 33, 55
Their sum is equals to
11 + 15 + 33 + 55 = 114
