How do you simplify the fraction \( \frac{36}{8} \)?

Back

To simplify \( \frac{36}{8} \), divide both the numerator and the denominator by their greatest common divisor, which is 4. This results in \( \frac{9}{2} \) or 4.5.

If a recipe calls for \( \frac{1}{3} \) cup of an ingredient, how much is needed for 3 times the recipe?

Back

For 3 times the recipe, multiply \( \frac{1}{3} \) by 3, resulting in 1 cup or \( \frac{3}{3} \) cup.

What is the formula for the area of a parallelogram?

Back

The formula for the area of a parallelogram is \( A = b \times h \), where \( b \) is the base and \( h \) is the height.

Front

How do you calculate the area of a triangle?

Back

The area of a triangle can be calculated using the formula \( A = \frac{1}{2} \times b \times h \), where \( b \) is the base and \( h \) is the height.

Front

What is the area of a triangle with a base of 8 units and a height of 5 units?

Back

The area is calculated as \( A = \frac{1}{2} \times 8 \times 5 = 20 \) square units.

Front

What does it mean to multiply a fraction by a whole number?

Back

Multiplying a fraction by a whole number means scaling the fraction by that whole number, effectively increasing the quantity represented by the fraction.

Front

What is the greatest common divisor (GCD)?

Back

The greatest common divisor (GCD) is the largest positive integer that divides each of the integers without leaving a remainder.

Front

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

Back

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient becomes the whole number, and the remainder becomes the new numerator.

Front

What is the relationship between area and units squared?

Back

Area is measured in square units, indicating that it is a two-dimensional measurement.
