1. Comparing & Scaling Inv. 1 Additional Practice
Learning Target:
I can solve proportions by scaling ratios.
Homework: Complete Inv. 1 Day 1 pg. 4 and CORRECT with the EDpuzzle.
Warm-Up:

2. .3 x 5 = 1.5in. .7 x 5 = 3.5in. .6 x 5 = 3in. .4 x 5 = 2in. x = 2in.10 3 + = =
.3 x 5 = 1.5in.
.7 x 5 = 3.5in.
60% + 40% = 100%
= 1
.6 x 5 = 3in.
.4 x 5 = 2in.
x + (x+1) = 5
2x + 1 = 5
2x = 4
x = 2
x = 2in.
x + 1 = 3in.

3. HW Review

7. About 53.3 or 53 attempts 10/15 = x/80 SF is about 5.3
E. Denzel makes 10 of his first 15 shots in a basketball free-throw contest. His success rate stays about the same for his next 100 free throws. Write and solve a proportion for each part. Round your answer to the nearest whole number.
Reading a table accurately!
a. About how many baskets do you expect Denzel to make in his next 60 attempts?
40 attempts /15 = x/ SF is 4
b. About how many free throws do you expect him to make in his next 80 attempts?
About 53.3 or 53 attempts 10/15 = x/80 SF is about 5.3

8. c. About how many attempts do you expect Denzel to take
to make 30 free throws?
45 attempts /15 = 30/x SF is 3
d. About how many attempts do you expect him to take
to make 45 free throws?
About 68 attempts 10/15 = 45/x SF is 4.5
