Question: When you do adding fractions, do you have to find a common demoniter? *sorry for misspelling*

docker41 [41]

Answer: yes when your adding or subtracting fractions you must find the common denominator between the two before you continue.

Step-by-step explanation:

Example: 2/4+3/2

Find the common denominator. ( in this case the common denominator is 4)

We keep the first fraction as it is cause it has the denominator 4 and we multiply the second fraction by 2 up and down to get a denominator of 4. The equation becomes 2/4+6/4

Now you add the numerators and you got your answer ( don’t forget to simplify)

The answer after adding in this case is 8/4 and when simplified it is 2

1400 dollars is placed in an account with an annual interest rate of 5.5%. to the nearest year, how long will it take for the ac

olga_2 [115]

It will take 19 years and 6 months for the account value to reach 2900 dollars

Step-by-step explanation:

Given

Principal amount = 1400 dollars

Rate = 5.5 %

Final value = A = 2900

We have to find t

So,

The formula for simple interest is:

$A = P(1+rt)$

Putting values

$2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t$

Dividing both sides by 0.055

$\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years$

Rounding off to nearest tenth

19.5 years

Hence,

It will take 19 years and 6 months for the account value to reach 2900 dollars
