How to convert 0.39 into a fraction?

Answers

Times it by 100 so you get 39.39/100 and then take off 1/100 which is 0.39 so your answer is 39/99 which you can then cancel down to 13/33. Hope this helps :)

What is 6 3/5 - 4 3/5

Answers

you do 3/5 minus 3/5 which cancels out to 0. Then you do 6 minus 4 which is 2. The answer is 2.

The answer is 2 because 6 3/5 - 4 3/5 = 2

Some one please help me with this problem. Thank you. NO answers, just explanation on how to solve it.

Answers

y = 3/2 t - 5/2 ; where t = 3

Substitute t by its value. the nearness of 3/2 to t denotes multiplication.

y = (3/2 *3) - 5/2

3 is a whole number. it is 3/1 in fraction form.
In multiplying fractions, simply multiply the numerator and the denominator.

y = (3*3 / 2*1) - 5/2
y = 9/2 - 5/2

Subtracting fractions: We can only subtract or add fractions if they all have the same common denominator. Since both fractions have 2 as denominator, we can proceed to subtracting its numerators.

y = (9-5)/2 *subtract numerators and place over the common denominator
y = 4/2 * simplify the fraction.
y = 2/1 or 2

George Inkling withdrew $550 simple interest from an account after 5 years. If he invested $3,437.50, how much was his rate of interest?

Answers

Answer:

His rate of interest(R) = 3.2%.

Explanation:

As per the given condition we have,

Interest withdrew(I)=$ 550 , Time(T)= 5 years , and the sum invested (P) = $3,437.50.

Use formula:

$I=(P * R * T)/(100)$

Substituting the above values to find the rate of interest (R);

$550=(3437.50 * R * 5)/(100)$ or

$R=(550 * 100)/(3437.50 * 5)$

On simplify we get;

R =3.2%

therefore, his rate of interest(R) is, 3.2%.

Mrs. Solar modeled Contractor 2’s fees with the formula y = 150 + 55x. Mrs. Solar compared Contractor 2’s fee to Contractor 1’s fee.

(a) What does the difference between 50 and 55 mean in the real-world context?
(b) What does the difference between 200 and 150 mean in the real-world context?

Answers

I'm guessing that you forgot to put contractor 1's fees
judging from the question, I would assume that his fees are y=200+50x
I will assume that y=fee and x=number of hours (or units of time)

so
a. difference between 55 and 50, that is 5 so #2's fee is 5$ more for every hour he works
b. difference between200 and 150 means that contractor 1 gets 50 more initally than contractor 2
