Answer:
5 / 8 = 0.625 is best equivalent.
4 = 2/4u
Multiply both sides by 4u
16u = 2
Divide both sides by 16, and simplify.
u = 1/8
<span>1). 16 x 3/4
Step One- 16/1 x 3/4
Step two- 4 goes into 16 four times so cancel the 4 and change the 16 to a 4...
Step three- 4 x 3=12
2). (81/16) divided by (9/14)
Step one- Since its division we use (FREEZE CLAP FLIP)= Freeze (81/16) Clap the division sign and change it to a multiply sign and Flip the riprocals (9/14)
The equation is now 81/16 X 14/9
Next 81 is divisible by 9 and 16 and 14 are divisible by 2
So the new formula i s 9/8 X 7/1
Solution=63/8
3). 2/3 divided by 4/3
Flip the reciprocals for the 4/3
New equation is 2/3 X 3/4
2 and 4 are divisible by 2 and the 3's cancel each other out
Solution: 1/2</span>
12.5=5x-3 1/3
5x=12.5+3 1/3
5x=15 5/6
5x=95/6
x=95/30 or simplied x=19/6
