Answer: what wrong
Step-by-step explanation:
Answer:
- 2730.54
- 18.8%
- 62.5% (decrease)
Step-by-step explanation:
The applicable formula is ...
rate = portion/base
so ...
base = portion/rate
Of course, a percentage is a fraction that has been multiplied by 100%.
__
1. base = portion/rate = 456/0.167 ≈ 2730.54
The base is about 2730.54.
__
2. rate = portion/base = 50/266 ≈ 0.18797 ≈ 18.8%
The rate is about 18.8%.
__
3. The decrease can be figured from ...
rate of change = (new amount)/(original) -1 = 33/88 -1
= -5/8 = -0.625 = -62.5%
The rate of decrease is 62.5%.

Answer:
D.
Step-by-step explanation:
To find this area, we can break it up into two rectangles, one with dimensions of 4x19 and another of 24x11. All we have to do is find the areas of both rectangles and add them together!
Since 4*19=76 and 11*24=264, we get D. 340 square units as our answer.
From the title of your worksheet, you have to convert improper fractions to proper fractions. So, you see those two numbers on the top and the bottom separated by a line? Those are fractions. For example, 12/4 is an improper fraction.(I can't use the exact 'line' that separates it as its not on my keyboard, so I'm just using '/'.) In 12/4, 12 is 'on top'. The number on top is the numerator. And the number on the bottom, 4, is the denominator. 12/4 is an improper fraction as the numerator is bigger than the denominator. So, you can divide 12 by 4, giving you 3. 3 is a whole number as 12 could be divided by 4 without remainder, so that's your answer if you wanted to convert it into a proper fraction. That's just an example, though. Another example for things that have remainder when divided; let's use 13/4 for this example. 13 can't be divided by 4 perfectly, so you use the closest number that can be divided by 4, which is 12. But what happens to the the number left after using 12? 13-12=1. That's where the fraction comes along. The denominator was 4 in 13/4 so the proper fractions that you get is 3(the whole number) and 1/4(the one left after using 12).
So, for that example, your answer's 3 1/4.(note that the whole number should be bigger than the fraction when you write it out.)
Sorry for this really long answer. I didn't want to just give you the answer without you understanding it.
Anyway, for your questions in your worksheet.
I'm starting from question 1 and not the example question in your worksheet.

( I put some spaces between the whole numbers and fractions so that it's not too complicating.)
I apologize if I made any mistakes ^^;;
Happy learning! :)
