What is the total weight of dog treats if each treat weighs 7 ounces and the box weighs 354.2 ounces?

Back

To find the number of treats, divide the total weight by the weight of each treat: \( \frac{354.2}{7} = 50.6 \) treats.

How do you calculate the height difference of a plant over two months?

Back

Subtract the height in May from the height in June. For example, if the height in May was 22 \( \frac{4}{12} \) inches and in June was 23 \( \frac{5}{12} \) inches, the difference is 23 \( \frac{5}{12} \) - 22 \( \frac{4}{12} \) = 1 \( \frac{1}{12} \) inches.

If Yasmin practiced ballet for 1 \( \frac{2}{3} \) hours on Monday and 2 \( \frac{1}{4} \) hours on Tuesday, how do you find the total practice time?

Back

Add the two times together: 1 \( \frac{2}{3} \) + 2 \( \frac{1}{4} \) = 3 \( \frac{11}{12} \) hours.

Front

How do you find the weight of an item if you know the total weight and the weight of another item?

Back

Subtract the known weight from the total weight. For example, if the total weight is 1 \( \frac{2}{15} \) pounds and the notebook weighs 0.8 pounds, the pencil box weighs 1 \( \frac{2}{15} \) - 0.8 = \( \frac{1}{3} \) pounds.

Front

What fraction represents the part of a whole?

Back

A fraction is a way to express a part of a whole, written as \( \frac{a}{b} \), where 'a' is the part and 'b' is the whole.

Front

What is the process to convert a mixed number to an improper fraction?

Back

Multiply the whole number by the denominator and add the numerator. For example, for 2 \( \frac{1}{3} \): (2 * 3) + 1 = 7, so it becomes \( \frac{7}{3} \).

Front

How do you add fractions with different denominators?

Back

Find a common denominator, convert the fractions, and then add the numerators. For example, to add \( \frac{1}{4} \) and \( \frac{1}{6} \), the common denominator is 12: \( \frac{3}{12} + \frac{2}{12} = \frac{5}{12} \).

Front

What is a survey and how is it used in data collection?

Back

A survey is a method of gathering information from individuals, often used to understand preferences or opinions, such as favorite foods.

Front

How do you find the fraction of a group that chose a specific option?

Back

Divide the number of people who chose that option by the total number of people surveyed. For example, if 7 out of 12 chose pizza, the fraction is \( \frac{7}{12} \).

Front

What is the significance of the numerator and denominator in a fraction?

Back

The numerator indicates how many parts are being considered, while the denominator indicates the total number of equal parts in the whole.
