Answer:
5 oranges in 12 minutes
Step-by-step explanation:
[tex]125 \div 5 = 25[/tex]
[tex]25 \div 60 = 0.41[/tex]
[tex]0.41 \times 12 = 5[/tex]
what i did here was I took the original amount (125), divided it by 5 which is 25 oranges per hour
1 hr = 60 mins
then I divided 25 oranges by 60 mins, then times it by 12 to get 5 around 5 oranges in 12 minutes.
Answer:
[tex]\boxed {\tt 5 \ oranges}[/tex]
Step-by-step explanation:
Let's set up a proportion.
[tex]\frac{oranges}{minutes} =\frac{oranges}{minutes}[/tex]
He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.
There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.
[tex]\frac{125 \ oranges}{300 \ minutes}=\frac{oranges}{minutes}[/tex]
We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.
[tex]\frac{125 \ oranges}{300 \ minutes}=\frac{x \ oranges}{12 \ minutes}[/tex]
[tex]\frac{125 \ }{300 \ }=\frac{x \ }{12 }[/tex]
Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.
[tex]12*\frac{125 \ }{300 \ }=\frac{x \ }{12 \ }*12[/tex]
[tex]12*\frac{125 \ }{300 \ }=x[/tex]
[tex]12*0.416666667=x[/tex]
[tex]5=x[/tex]
Rob can peel 5 oranges in 12 minutes.
