Find the Least Common Multiple
The left denominator is : 4
The right denominator is : 6
Number of times each prime factor
appears in the factorization of:
Prime
Factor Left
Denominator Right
Denominator L.C.M = Max
{Left,Right}
2 2 1 2
3 0 1 1
Product of all
Prime Factors 4 6 12
Least Common Multiple:
12
Calculate multipliers for the two fractions
Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Denominator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 3
Right_M = L.C.M / R_Deno = 2
Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction, multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 9 • 3
—————————————————— = —————
L.C.M 12
R. Mult. • R. Num. 17 • 2
—————————————————— = ——————
L.C.M 12
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
9 • 3 - (17 • 2) -7
—————— = ——

Answer:
0.5 is 0.25% of 200.
Step-by-step explanation:
1 is 1/200 of 200.
Therefore, 0.5 is 1/400 of 200.
1/400 = 0.0025 = 0.25/100
Therefore, 0.5 is 0.25% of 200.

6. At the Winter Olympics, the ratio of Canadian medals to US to Russia was 1:8:5. If Russia won 25
medals, how many did Canada and US won?
Answers
Answer:
Step-by-step explanation:
Let x be the total number of medals won by the Russians.
The way to do this is to add the ratios together
1 + 8 + 5 = 14
(5/14) x = 25
Multiply by 14
5*x = 25 * 14
5x = 350
divide by 5
70
8/14 = x / 70
14x = 8 * 70
14x = 560
x = 560 / 14
x = 40
The USA won 40 medals.
1/14 = x / 70
14x = 70
x = 5
Canada Won 5 medals.
Check
Russia Won 25 medals
Canada Won 5 medals
USA Won 40 medals

Cindy is make a display for a project. She plans on 100 stickers that are 2 inch by 2 inch square on a poster board. The poster board she is using has a length of 3 feet and width of 2 feet. Does she have enough room for all her stickers
Answers
Answer:
YES
Step-by-step explanation:
the dimensions of the poster board has to be converted to inches to add comparability
1 feet = 12 inches
3 x 12 = 36 inches
width = 2 x 12 = 24 inches
Area = length x breadth
36 x 24 = 864 cm^2
area of sticker = 2 x 2 = 4cm^2
Number of stickers that can be put on the board = 864 / 4 = 216
216 is greater than 100. So the board has enough room for the stickers

Julio bought 7 science fiction novels (s) and 7 comic books (c) from the bookstore. His purchases can be represented by the expression 7(s + c). Part A: Simplify the expression by using the distributive property. Part B: The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. What is the total amount that Julio spent at the bookstore? Round your answer to the nearest cent. Show your work.
Answers
Answer: See explanation
Step-by-step explanation:
A. 7(s + c)
= 7s + 7c
B. The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. The total amount that Julio spent at the bookstore would be calculated as:
= 7s + 7c
= 7($5.99) + 7($6.49)
= $41.93 + $45.43
= $87.36
We then add tax which will then be:
= $87.36 + (6% × $87.36)
= $87.36 + (0.06 × $87.36)
= $87.36 + $5.24
= $92.60

Cameron's hourly salary is $13. If Cameron
gets to work in the morning at 9 has lunch
from 12 to 1. and then works until 2. then hou
much did Cameron make that day?
Answers
Answer: 52 dollars
Step-by-step explanation:
Cameron's hourly salary is 13, which means that for each hour she works, she earns 13 dollars.
If she words from 9 - 12, then that is 3 hours. Then she has a lunch break from 12 - 1, and then works again until 2. The time period between 1 and 2 o'clock is 1 hour.
Now we have to add up the total hours that Cameron works. If she worked 3 hours in the morning, and then 1 hour after lunch, then the total is 4 hours. Now we have to mutliply 4 by 13 to find her salary for that day.
4 x 13 = 52. Therefore, Cameron made 52 dollars that day.
