Friday, Sept 12 Lesson Estimate with Percents
Objective: To estimate the percent of a number.
Estimate with Percents When estimating with percents, choose comparable numbers. Example 23% of % of 200 of 200
Estimate with Percents When estimating with percents, choose comparable numbers. Estimating with percents will provide a reasonable solution to many real-world problems.
Estimate with Percents Estimate 47% of 692. Step 1 - Choose comparable numbers. (Choose a comparable number for the percent that is easily converted to a fraction.)
Estimate with Percents Estimate 47% of % of 700 Step 1 - Choose comparable numbers. (Choose a comparable number for the percent that is easily converted to a fraction.)
Estimate with Percents Estimate 47% of % of 700 Step 2 – Convert the percent to a fraction and simplify.
Estimate with Percents Estimate 47% of % of 700 of 700 Step 2 – Convert the percent to a fraction and simplify.
Estimate with Percents Estimate 47% of % of 700 of 700 Step 3 – Mentally divide the number by the denominator, then multiply by the numerator. You may have to change the number to make it easily divisible by the denominator.
Estimate with Percents Estimate 47% of 692 ≈ % of 700 of 700 = of means to divide by 2
Estimate with Percents Estimate 60% of 27. What is first?
Estimate with Percents Estimate 60% of % of 25 Next?
Estimate with Percents
≈ 15
Estimate with Percents Estimate 48% of 76. Do this on your own.
Estimate with Percents Estimate 48% of 76 ≈ 40 50% of 80 ½ of 80 is 40
Estimate with Percents Estimate 18% of 42. Do this on your own.
Estimate with Percents ≈ 8
Estimate with Percents Estimate 73% of 41. Do this on your own.
Estimate with Percents ≈ 30
Estimate with Percents Estimate 72% of 400. (Do this on your own)
Estimate with Percents Estimate 72% of 400 ≈ % of 400 of 400 is 300
Estimate with Percents Estimate 31% of 124. (Do this on your own)
Estimate with Percents Estimate 31% of 124 ≈ 40 33% of 120 of 120 = 40 Or you may have 31% of % of 120 of 120 = 36
Estimate with Percents Estimate the percent of the shaded area.
Estimate with Percents Estimate the percent of the shaded area. It looks like the shaded area is 1 of 3 equal sections, or 33%.
Estimate with Percents Estimate the percent of the shaded area.
Estimate with Percents Estimate the percent of the shaded area. It looks like the shaded area is 3 of 4 equal sections, or 75%.
Estimate with Percents Polar bears can eats as much as 10% of their body weight in one hour. If an adult bear weighs 715 pounds, about how much can it eat in one hour? Do this on your own.

Estimate with Percents In some situations, we can estimate by using a rate per 100. Estimate 17% of 198.
Estimate with Percents Estimate 17% of % of 100 is 17 and since 198 is about 2 x 100, Then 17% of 200 = 2 x 17 = 34
Estimate with Percents An airline records the snack orders for passengers. Last year 9% of all passengers ordered ginger ale to drink. There are 408 passengers on a flight to Houston. About how many passengers does the airline expect to order ginger ale on this flight? Do this on your own.

About how many passengers does the airline expect to order ginger ale on this flight? Estimate 9% of 408 9% = 9 out of 100 and 408 is about 400 Since 400 is 4 x 100, multiply 4 x is about 9% of 408
