Answer:

40

Step-by-step explanation:

Set up the equation.

Let the full number of people in the classroom = x

(40%) x = 16                Change 40% to a fraction

(40/100) x = 16            Reduce 40/100 to a decimal

0.4 x = 16                     Divide by 0.4

0.4/0.4 x = 16/0.4

x = 40

Studentka2010 [4]

Answer:

a) 120 words per minute

b) 130 words per minute

Jasmine reading unit rate = 120 words / 1 minute = 120 words per minute

b) It takes Scott one minute to read 130 words

Scott reading unit rate = total number of words read / time taken

Scott reading unit rate = 130 words / 1 minute = 130 words per minute
