Solutions
1) The first step is to find the Least Common Denominator (LCD) of <span>3/8,1/8,1/3,1/4
</span>⇒ Start Listing Multiples
List out all multiples of each denominator, and find the first common one.
8: <span><span>8,16,24</span>
</span>
8 : <span>8,16,24
</span>
3 : <span>3,6,9,12,15,18,21,24
</span>
4 : <span><span>4,8,12,16,20,24</span>
</span>
Therefore, the LCD is <span>24
</span>⇒ By Prime Factors
List all prime factors of each denominator, and find the union of these primes.
8 : <span>2,2,2</span>
8 : <span>2,2,2</span>
3 : 3
4 : <span><span>2,2</span>
</span>
Therefore, the LCD is <span>2×2×2×3=24
</span>Make the denominators the same as the LCD
<span><span><span>3×3 / </span><span>8×3 </span></span>+<span><span>1×3 / </span><span>8×3 </span></span>−<span><span>1×8 / </span><span>3×8 </span></span>+<span><span>1×6 / </span><span>4×6
</span></span></span>Simplify. Denominators are now the same
<span><span>9 / 24</span>+<span>3 / 24</span>−<span>8 / 24</span>+<span>6 / 24
</span></span>Join all the denominators
<span><span>9+3−8+6 / </span>24
</span>Simplify
<span>10 / 24
</span>Simplify fraction 10 / <span>24</span>
<span>5 / 12</span>
Given:
Kate wants to buy some daisies for $6.99, some potting soil for $3.98, and a ceramic pot for $7.95. She has $20.00
Required:
Amount of change Kate receives back?
Explanation:
We will add each expense
Now, amount of change Kate receives back is 20.00 - 18.92 = 1.08
Answer:
Hence, amount of change Kate receives back is 1.08
Answers: #2, 3, 5, 6 are correct
... believe me, I juss did them.
Answer: About 43% of the paintings are displayed on the first floor.
Step-by-step explanation: For this problem we can use a percent equation to solve for p, the percent of paintings that will be displayed on the first floor.
Lets write the percent equation:
40/92 = p/100 (We basically are finding 40 out of 92 paintings is what percent of the total paintings.
40/92 x 100 = p/100 x 100 (We always multiply both sides by 100 when dealing with percent that are out of a whole, or 100.)
40 x 100 = 4000/92 = ABOUT 43. p/100 x 100 = p.
About 43 = p
So about 43% of the paintings are displayed on the first floor.
