Basile [38]

Answer: x=2

Step-by-step explanation:

Equation: 5x/3-7x/12=13/16

What's 10% ÷ 0.1%. I can't figure out why it's 10,000%.​
Debora [2.8K]

Answer:

10/100 ÷ 1/1000

Copy dot flip

10/100 * 1000/1 =

10000/100

100

Now we need to change it to percent

Multiply by 100%

100 * 100 %

10000%
