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

The distance d, in meters, that a rhinoceros runs in s seconds is represented by the equation d=16s. What is the constant of pro

castortr0y [4]

Time Distance Distance / Time
2hrs 90 miles 90 miles / 2 hrs = 45 miles / hr
3hrs 135 miles 135 miles / 3 hrs = 45 miles / hr
5hrs 225 miles 225 miles / 5 hrs = 45 miles / hr
6hrs 270 miles 270 miles / 6 hrs = 45 miles / hr

Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.

Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt
Constant of proportionality is k which is D/T
d = 45t

Raphel wants a new care, he needa a down payment of $3,000.If he saves $340 each month, about how many months will it take him t

Andre45 [30]

Hello! I would love to help!

Okay, we know that Raphel has to pay 3,000 dollars in a certain amount of months. Let's let "m" represent the amount of months it will take him.

Now, if we know that he saves 340 dollars a month, we can multiply the unknown amount of months, "m" by 340 to find how many will get 3000.

Here's our equation:

340m = 3000

Alright let's solve for m.

Divide both sides by 340.

340m/340= m

3000/340=8.824

So know we know m= 8.824, or exactly 8.824 months to save 3000 dollars.

However, it is really hard to count 8.824 parts of a month. Let's round it to the nearest whole, nine.

So, that means your answer is 9 months!

Hope this helped! Comment if you have questions!
