Martin was given 10 math problems, and he has answered 7 of them. What percent of the problems does Martin have left to do?
Responses
A 3%3%
B 7%7%
C 30%30%
D 70%
explain how u got ur answer
To find the percentage of problems that Martin has left to do, we need to calculate the percentage of problems he has already done and subtract it from 100%.
Martin has answered 7 out of 10 problems, so the percentage of problems he has already done is (7/10) * 100 = 70%.
To find the percentage of problems he has left to do, we subtract this percentage from 100%: 100% - 70% = 30%.
So the correct answer is:
C 30%
The part of the wedding cake not eaten by the guests is represented by 0.02. Which fraction represents the part of the cake the guests did not eat?
Responses
A 1/50
1 50
B 1/5
1 5
C 2/1000
2 1000
D 2/10
To find the fraction that represents the part of the cake the guests did not eat, we need to convert the decimal 0.02 to a fraction.
0.02 can be written as 2/100, since the decimal point is two places to the right of the number 2.
To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 2.
When we divide 2/100 by 2, we get 1/50.
So the correct answer is:
A 1/50
how do u divide a fraction by a whole number
To divide a fraction by a whole number, you can rewrite the whole number as a fraction with a denominator of 1 and then use the rules of fraction division.
For example, if you have the fraction 2/3 and you want to divide it by the whole number 4, you can rewrite 4 as a fraction: 4/1.
To divide the fractions, you can multiply the first fraction by the reciprocal of the second fraction:
(2/3) ÷ (4/1) = (2/3) * (1/4)
To multiply the fractions, you multiply the numerators together and the denominators together:
(2/3) * (1/4) = (2 * 1) / (3 * 4) = 2/12
In this case, the result is 2/12, which can be simplified to 1/6.
So, when you divide a fraction by a whole number, you can divide the numerator by the whole number and keep the same denominator.

To represent 0.35 as a fraction, we need to determine the fraction equivalent of the decimal.
First, we can place 0.35 over 1 to represent it as a fraction: 0.35/1.
Next, we need to eliminate the decimal point. Since there are two decimal places in 0.35, we can multiply both the numerator and denominator by 100 to remove the decimal: (0.35 * 100) / (1 * 100) = 35/100.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common factor, which is 5: (35/5) / (100/5) = 7/20.
So, the correct answer is:
B 7/20

Explanation: Each of these numbers represents the same value. 18 is equal to 0.8, which is equal to 80% when expressed as a percentage.
18 is 1 over 8
I apologize for the mistake. You are correct. The correct answer is:
A 1/5, 0.2, 20%
Explanation: Each of these numbers represents the same value. 1/5 is equal to 0.2, which is equal to 20% when expressed as a percentage.
There are 0.25 quart in one cup.
Which fraction is equivalent to the number of quarts in one cup?
Responses
A 25
2 fifths
B 14
1 fourth
C 23
2 thirds
D 18
To find the fraction equivalent to the number of quarts in one cup, we can write it as a fraction with the same units.
Since there are 0.25 quarts in one cup, it can be written as 0.25/1.
To simplify this fraction, we can multiply both the numerator and denominator by 4 to eliminate the decimal: (0.25 * 4) / (1 * 4) = 1/4.
So, the correct answer is:
B 1 fourth
In Jamie's class, 1/5
of the students are boys. What percent of the students in Jamie’s class are boys?
To find the percent of students in Jamie's class who are boys, we can convert the fraction 1/5 to a percentage.
To do this, we can multiply the fraction by 100%:
(1/5) * 100% = (1 * 100) / 5 = 100/5 = 20%.
So, 20% of the students in Jamie's class are boys.

To find the fraction equivalent to the amount of popcorn in cups that a small popcorn holds, we can write it as a fraction with the same units.
Since a small popcorn holds 0.72 cup of popcorn, it can be written as 0.72/1.
To simplify this fraction, we can multiply both the numerator and denominator by 100 to eliminate the decimal: (0.72 * 100) / (1 * 100) = 72/100.
We can further simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 4: (72/4) / (100/4) = 18/25.
So, the correct answer is:
B 18 over 25
