Answer:

$\frac{12}{20}$

Step-by-step explanation:

Lets think about multiplication. What times 5 equals 20? (5x = 20)

It would be 4! (5 x 4 = 20)

So take the 4 and multiply it by the fraction.

$4 * \frac{3}{5} = \frac{4}{4} * \frac{3}{5} = \frac{12}{20}$

Theres your answer :)

1/2 - 3/4 equals what

n200080 [17]

1. Method 1: By Listing MultiplesList out all multiples of each denominator, and find the first common one.

2: 2 , 4

4: 4
Therefore, the LCD is 4

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.
Therefore, the LCD is 2 x 2 = 4

2. Make the denominators the same as the LCD

 $\frac{1 x 2}{2 x 2} - \frac{3}{4}$

3. Simplify. Denominators are now the same.

 $\frac{2}{4} - \frac{3}{4}$

4. Join the denominators

$\frac{2-3}{4}$

5. Simplify

 $-\frac{1}{4}$

Done! :) Decimal Form: -0.25

Solve the following equation and show all the steps to solving.

Bumek [7]

$\bf \cfrac{x}{x-2}+\cfrac{x-1}{x+1}=-1\impliedby LCD\to (x-2)(x+1)\\\\
-------------------------------\\\\
\cfrac{x(x+1)+(x-1)(x-2)}{(x-2)(x+1)}=-1
\\\\\\
x^2+x+x^2-3x+2=-1(x-2)(x+1)
\\\\\\
2x^2-2x+2=-1(x^2-x-2)\implies 2x^2-2x+2=-x^2+x+2
\\\\\\
3x^2-3x=0\implies 3x(x-1)=0\implies 
\begin{cases}
3x=0\implies &x=0\\
x-1=0\implies &x=1
\end{cases}$

Gianna put $1000 in a savings account for 18 months, The interest on the account is 3.5%. How much will Gianna earn in interest?

zimovet [89]

Answer:

amount of interest = 52.5

amount at the end of the period = 1052.5

Step-by-step explanation:

use the formula for simple interest

PRT/100

P is the principle

R is the rate of interest charged

T is the Time taken

18 months = 1 years 6 months ( 1.5 years)

1000 * 3.5 * 1.5 = 5250

5250/100 = 52.5

the amount of interest = 52.5

the amount she will have at the end of the period

= 1000 +52.5

= 1052.5
