Step-by-step explanation:. The first says “I know that 10 is one-tenth of 100. I will therefore divide 50 by 10. The answer is 5”.
This is fine when the numbers are relatively simple. But suppose the numbers are more complicated.
What is 22% of 46?
Now it’s much less straightforward. You can’t just work out what 22% is, expressed as a fraction, and anyway, it’s not a simple fraction.
Instead, you have to divide 46 into 100 equal parts, and work out what 22 of them would be when added together.
So: 46 ÷ 100 = 0.46 [remember, when you divide by 100, you move the decimal point two places to the left].
0.46 × 22 = 10.12
Answer: 22% of 46 is 10.12.
Hope this helped :)
Answer:
it's true! it's easier to solve for y because there's no coefficient in front of it unlike the second one that has "9y."
Answer:
The cost of an egg is $0.11
Step-by-step explanation:
Given : The cost of one dozen of eggs is $ 1.35
We have to find the cost of one egg.
We know, one dozen has 12 units
Thus, One dozen of eggs contain 12 eggs
So cost of 12 eggs is $ 1.35
So to find the cost of one egg divide the cost by 12.
We get,
1 egg = 
Thus, The cost of an egg is $0.11
