Answer:
two different shades of what I think is pink.
1/3 is equal to 2/6 which is equal to 3/9
1/2 is equal to 2/4 which is equal to 4/8
The bolded ones are the original mixtures given.
Start with 1/3 Multiply top and bottom by 2 and you get 2/6
When you multiply top and bottom of 1/3 by by 3 you get 3/9
Use the same idea for 1/2
Step-by-step explanation:
Start with 1/3 Multiply top and bottom by 2 and you get 2/6
When you multiply top and bottom of 1/3 by by 3 you get 3/9
Use the same idea for 1/2.
I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7
II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)
