What fraction is greater than 1/2 but less than 3/4
aliya0001 [1]
1/2 = 50%

3/4 = 75%

So something in between that could be 2/3 (which equals 66.67% )

A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%) 

Hope that helps :)

Rob peeled 125 oranges in 5 hours. At that rate, how many oranges<br> would he peel in 12 minutes?
marin [14]

Answer:

\boxed {\tt 5 \ oranges}

Step-by-step explanation:

Let's set up a proportion.

\frac{oranges}{minutes} =\frac{oranges}{minutes}

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.

\frac{125 \ oranges}{300 \ minutes}=\frac{oranges}{minutes}

We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.

\frac{125 \ oranges}{300 \ minutes}=\frac{x \ oranges}{12 \ minutes}

\frac{125 \ }{300 \ }=\frac{x \ }{12 }

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.

12*\frac{125 \ }{300 \ }=\frac{x \ }{12 \ }*12

12*\frac{125 \ }{300 \ }=x

12*0.416666667=x

5=x

Rob can peel 5 oranges in 12 minutes.

What is the name of a polygon that has four congruent sides and theses angle measures 60,120,60,120?
svetlana [45]

<u>Answer:</u>

The correct answer for this is: rhombus.

<u>Step-by-step explanation:</u>

The name of a polygon that has four congruent sides with the angles measuring 60°, 120°, 60° and 120° is rhombus.

According to the properties of a rhombus, the opposite angles are equal and opposite sides are parallel.

However, the adjacent angles of rhombus are supplementary which means that they add up to 180°.

For example:

60° + 120° = 180°
