First you had to switch sides of equation form.
[tex]\frac{x}{100}= \frac{7}{10}[/tex]
Then you multiply by one-hundred from both sides of equation form.
[tex]\frac{x}{100}*100= \frac{7}{10}*100[/tex]
And finally, simplify by equation.
[tex]\frac{x}{100}*100=x[/tex]
[tex]\frac{7}{10}*100=70[/tex]
[tex]70*1=70[/tex]
[tex]x=70[/tex]
Final answer: [tex]\boxed{x=70}[/tex]
[tex]70/10=7[/tex]
[tex]70/7=10[/tex]
[tex]10*7=70[/tex]
[tex]7*10=70[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

x = 70
given [tex]\frac{7}{10}[/tex] = [tex]\frac{x}{100}[/tex] ( cross-multiply )
10x = 7 × 100 = 700 ( divide both sides by 10 )
x = [tex]\frac{700}{10}[/tex] = 70
