Answer:
7
Step-by-step explanation:
126 g is what you originally had which=60% of whats left
you have to find out how many 10 wedges she can cut from the cheese that is left over
Work Shown:to find how much is left you have to multiply 126 by 60% remember when you multiply you have to move the decimal, and decimal is moved twice, so the answer would be 75.60 after you were done solving it and the number that is closest would be 70 so you would multiply 10 by 7=70 and the reason you pick that is because it is closer to 75.60.
So 7 is the answer.
40$ - 100% (full price)
x$ - 70% (100-30=70%)
40 * 70 = 100x
2800 = 100x
x = 28
Answer 28$
or
40$ = 100%
then 1% = 40/100 = 0.4$
so 70% will be 0.4 * 70 = 28$
The answer is 31. It is obvious. Have a nice day.
It's different because they have 2 different numbers<span />
It is 27/6 or 4 1/2. you just need to subtract the numerators because you have a common denominator
