Front

What is the process to divide a fraction by a whole number?

Back

To divide a fraction by a whole number, multiply the denominator of the fraction by the whole number. For example, to divide 1/2 by 4, calculate 1/(2*4) = 1/8.

Front

How do you find a fraction of a whole number?

Back

To find a fraction of a whole number, multiply the whole number by the numerator of the fraction and then divide by the denominator. For example, to find 1/4 of 12, calculate (1*12)/4 = 3.

Front

What is the total amount when adding fractions with different denominators?

Back

To add fractions with different denominators, find a common denominator, convert the fractions, and then add the numerators. For example, 1/4 + 1/3 = 3/12 + 4/12 = 7/12.

Front

What is the meaning of 'per pound' in pricing?

Back

'Per pound' means the cost of one pound of an item. For example, if bananas cost $0.68 per pound, then 4.5 pounds would cost 4.5 * $0.68 = $3.06.

Front

How do you calculate the total amount of pizza eaten by multiple people?

Back

To calculate the total amount of pizza eaten by multiple people, multiply the amount each person eats by the number of people. For example, if 5 boys each eat 2/3 of a pizza, the total is 5 * (2/3) = 10/3 = 3 1/3 pizzas.

Front

What does it mean to take away in a subtraction problem?

Back

To take away means to subtract a number from another. For example, if you have 4 apples and take away 3, you subtract 3 from 4, leaving you with 1 apple.

Front

How do you determine what fraction of a total is represented?

Back

To determine what fraction of a total is represented, divide the part by the whole. For example, if 3 out of 12 pizzas have mushrooms, the fraction is 3/12, which simplifies to 1/4.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together. For example, if 4.5 pounds of bananas cost $3.06, the unit rate is $3.06/4.5 pounds.

Front

How do you convert a mixed number to an improper fraction?

Back

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place that over the original denominator. For example, 3 1/3 = (3*3 + 1)/3 = 10/3.

Front

What is the importance of understanding word problems in math?

Back

Understanding word problems is crucial because they require translating real-life situations into mathematical expressions and equations, helping to develop problem-solving skills.
