๐Ÿงฎ Quick Study Guide

  • โž— A rate is a ratio that compares two quantities with different units.
  • โœ๏ธ A unit rate is a rate with a denominator of 1. For example, if you travel 120 miles in 2 hours, the unit rate is 60 miles per hour.
  • โž— To find a unit rate, divide the numerator and the denominator of the rate by the denominator. For example, to find the unit rate for $\frac{120 \text{ miles}}{2 \text{ hours}}$, divide both the numerator and denominator by 2: $\frac{120 \div 2}{2 \div 2} = \frac{60 \text{ miles}}{1 \text{ hour}}$.
  • ๐Ÿ’ฐ You can use unit rates to solve problems involving proportional relationships. For example, if you know the unit price of an item, you can multiply the unit price by the number of items to find the total cost.
  • ๐Ÿ“ Unit rates are useful for comparing different rates. For example, if one store sells apples for $2 per pound and another store sells apples for $3 per 2 pounds, you can compare the unit rates ($2 per pound vs. $1.50 per pound) to see which store has the better deal.

  • โฑ๏ธ A rate is a ratio that compares two quantities with different units.
  • โž— A unit rate is a rate where the second quantity is 1. To find a unit rate, divide the first quantity by the second quantity.
  • ๐Ÿ’ฒ You can use unit rates to solve problems involving proportional relationships. For example, if apples cost $\$2.00$ per pound, you can find the cost of 5 pounds of apples by multiplying $5 \times \$2.00 = \$10.00$.
  • ๐Ÿš€ To compare rates, convert them to unit rates. The rate with the larger value is the better deal.
  • ๐Ÿ“ Formula for Unit Rate: $\text{Unit Rate} = \frac{\text{Quantity 1}}{\text{Quantity 2}}$
  • ๐Ÿค Proportional Relationships: Quantities are proportional if their ratios are constant. That is, $\frac{y}{x} = k$, where $k$ is the constant of proportionality.

    ๐Ÿ”ข Unit Rate Definition: A unit rate compares a quantity to one unit of another quantity. It tells you how much of something you get for 1 unit of something else. โž— Calculating Unit Rates: To find the unit rate, divide the quantity by the number of units. For example, if you travel 120 miles in 2 hours, the unit rate is $120 \div 2 = 60$ miles per hour. ๐Ÿ’ฐ Unit Price: A unit rate that tells you the cost of one item. If a pack of 6 apples costs $3, the unit price is $3 \div 6 = $0.50$ per apple. โš–๏ธ Comparing Unit Rates: When comparing options, choose the one with the lower unit cost or higher quantity per unit, depending on what you're looking for. ๐Ÿ“ Formula: Unit Rate = $\frac{\text{Quantity}}{\text{Number of Units}}$
