Six fifths of what number is 60?
Crazy boy [7]
<h3>Hey Buddy,</h3>

<h3>Answer :-</h3>

Answer is 72 .

<h3><u>Explanation :-</u></h3>

\frac{6}{5}  \: of \: what \: number \: is \: 60 \:

You probably , Know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well .

• Any number can be converted to fraction if you use 1 as the denominator:

\frac{60}{1}

• So now that we've converted 60 into a fraction, to work out the answer, we put the fraction 6/5 side by side with our new fraction, 60/1 so that we can multiply those two fractions.

• convert the whole number to a fraction and then multiply the numerators and denominators.

\frac{6 \times 60}{5 \times 1}  =  \frac{360}{5}

• Our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

• You can use our handy GCF calculator to work this out yourself if you want to. We already did that , And the GCF of 360 and 5 is 5.

• We can now divide both the new numerator and the denominator by 5 to simplify this fraction down to its lowest terms.

\frac{360}{5}  = 72

\frac{5}{5}  = 1

• When we put that together, we can see that our complete answer is :-

\frac{72}{1}

<h3> Hence ,the complete and simplified answer to the question what is 6/5 of 60 is :- 72 .</h3>

<h3>Hope this helps you...!</h3>

mary lou is twice geoge's and kate is two years younger than george the sum of all of their ages is 46 how old is everyone​
saw5 [17]

Answer:

George is 12, Mary Lou is 24 and Kate is 10.

Step-by-step explanation:

To find these, start by setting George's age as x. This means that we can model Mary Lou's age as 2x, since she is twice as old. We can also model Kate's age as x - 2 since she is two years younger. Now we can add these 3 together and set equal to 46

x + 2x + x - 2 = 46

4x - 2 = 46

4x = 48

x = 12

This means that George is 12.

Mary Lou = 2x

Mary Lou = 2(12)

Mary Lou = 24

Kate = x - 2

Kate = 12 - 2

Kate = 10

Please help me this is so confusing to me.
Naddik [55]

Hi there! :)

\large\boxed{A = 120^{o}}

Find the central angle using a ratio in regards to angle and circumference.

The radius is 27 units, so use the following equation to calculate circumference:

C = 2rπ

Therefore:

C = 2(27)π = 54π

Since we have the total circumference, we can write the following proportion:

\frac{x}{360} = \frac{18\pi}{54\pi}

Cross multiply:

54πx = 6480π

Divide both sides by 54π to isolate for x:

x = 120°
