Help me pleaseeeeeee! Ratios and Rates! Worth 20 points help I need the answers in 45 minutes!

Answer 1

Answer:

look at explanation, oh and pls give brainlist

Step-by-step explanation:

3.   7:8  $\7\frac{7}{8}$ ,7 to 8

4.  $\frac{100 l}{40 w}$, $\frac{25}{10}$, $\frac{50}{20}$

5.  $\frac{2 hrs}{120 m}$, unit rate= 60 miles per hour, $\sqrt[2]{120}$=60

6.  $\sqrt[3]{900}$= 300, 300x3=900, unite rate= 300km per hour

7.  $\frac{50}{5}$=$\frac{10\\}{1}$, unit rate for Tim= $10 for 1 hour, $\frac{24}{2}$=$\frac{12}{1}$, unit rate for Jane= $12 for 1 hour, Jane has the higher rate of pay.

8. $\frac{65}{4}$=$\frac{16.25}{1}$ , $\sqrt[4]{65}$= 16.25, unit rate for Jon is 16.25ths of a pushup per minute.

$\frac{45}{3}$=$\frac{15}{1}$, $\sqrt[3]{45}$=15, unit rate for Paul is 15 pushups per minute.

Jon can do more pushups in 1 minute

Answer 2

Answer:

3) 7:8  7 to 8   4) 40/100 = 2/5   5) 60 mph   6) 300 kph   7) Jane  8) Jon can go faster

Step-by-step explanation:

5) 120/2 =60

6) 900/3 =300

7) Tim =50/5= $10 an hour

Jane= 24/2 =$12 an hour
