Solve 6/7 divided 36/56 and put answer in simplest form A.8/6
B.2/8
C.6/8
D.4/3

Answers

Answer:

Solve $(6)/(7)$ divided $(36)/(56)$ and put answer in simplest form

D. $(4)/(3)$

Step-by-step explanation:

The easily technique for dividing fractions is invert one of the fraction and multiply the fractions. Numerator should be multiplied by the other numerator and denominator should be multiplied by the other denominator after invert one of the fraction.

$(6)/(7)$ ÷ $(36)/(56)=(6)/(7)*(56)/(36)$

$(6)/(7) * (56)/(36)=(336)/(252)$

Now, we need to simplify the fraction. The numerator and the denominator are divisible between two,

Therefore:

$(336)/(252)=(168)/(126)$

The numerator and the denominator are divisible between two,

Therefore:

$(168)/(126)=(84)/(63)$

The numerator and the denominator are divisible between 3,

Therefore:

$(84)/(63)=(28)/(21)$

The numerator and the denominator are divisible between 7,

Therefore:

$(28)/(21)=(4)/(3)$

Now, we have found the answer:

D. $(4)/(3)$

The simplified form of the expression 6/7 divided 36/56 is 4/3.

Option D.4/3

What is the simplified form of the expression?

Given the expression in the question:

6/7 divided 36/56

Which is the same as:

6/7 ÷ 36/56

To solve the division problem (6/7) ÷ (36/56), multiply the first fraction by the reciprocal of the second fraction:

Hence:

6/7 ÷ 36/56

6/7 × 56/36

Multiply the denominators and then multiply the numerators:

( 6 × 56 ) / ( 7 × 36 )

Simplifying, we get:

336/ ( 7 × 36 )

336 / 252

Simplify:

4/3

Therefore, the simplified form is 4/3.

Option D) 4/3 is the correct answer.

Over twenty years, it was found that the number of doctors of medicine, MD (in thousands), in the United States can be approximated by MD=(28,390+693t)/(85-t) where t=0 represents 1980. The number of doctors of osteopathy, DO (in thousands), can be approximated by DO=(776-12t)/(65-2t) .Write an expression for the total number I of doctors of medicine (MD) and doctors of osteopathy (DO). Simplify the result.

How many MDs did the United States have in 2010? How many MDs did the United States have in 2010?

Answers

The expression for the total number of doctors is $(-1374t^2+43192.22t+67805.35)/((65-2t)(85-t) )$

We have to write an expression for the number of MD and DO

a. MD + DO

$(28390+693t)/(85-t) +(776-12t)/(65-2t)$

This can be simplified as

$((28390+693t)(65-2t)+(776-12t)(85-t) )/((85-t)(65-2t) )$

$= (-1374t^2+43192.22t+67805.35)/((65-2t)(85-t) )$

b. If t = 0 in 1980, in 2010, t = 30

The number of MD would be

$(28390+693*30)/(85-30) \n= 379$

The number of DO would be

$(776-12*30)/(65-2*30)\n\n= 83$

Brad and Wes are building a tree house. They cut a 12 1/2 foot piece of wood into 5 of the same length. how long is each piece of wood? show your work

Answers

Answer:

$2(1)/(2)$ foot

Step-by-step explanation:

Brad and Wes cut a $12(1)/(2)$ foot piece of wood into 5 of the same length.

Let length of 1 piece be x

So, Length of 5 pieces = 5x

Total length of wood= $12(1)/(2)=(25)/(2)$

So, $5x=(25)/(2)$

$x=(5)/(2)$

$x=2(1)/(2)$

Hence Length of each piece is $2(1)/(2)$ foot

This is what I did
I divided 12.5/5=2.5 and each pieces of wood would be 2.5 FT.
