Step-by-step explanation:
Answer: 62,390
Step-by-step explanation:
You Need To Create An Equation Then Solve For Their Rates Of Travel.
Subtract 79 from both sides to isolate variable b.
b = 159 - 79
b = 80
Answer: Simplifying ratios is just like simplifying fractions. Think of ratios as fractions. You divide a number that both numerator and denominator can be divided by.
<u>Example</u>
5/10 = 1/2
How did we get 1/2? Simple! You divide the numerator and denominator by 5.
5/10÷5/5=1/2
You do the same for ratios but the only difference is instead of putting a fraction bar (/) you put a colon (:)
Let's try another example but with a ratio!
<u>Example</u>
5:10 = 1:2
How did we get 1:2? Simple! Again we divided by 5 just like we did with the fraction example! So really ratios are just like fractions!
5:10÷5:5=1:2
<u>Remember</u>
The fraction bar is /
The ratio bar is :
Ratios are just like fractions but the symbol can sometimes trick people.
