Answer:
[tex]\frac{120}{100}\times x=78[/tex] or [tex]12x=780[/tex]
Step-by-step explanation:
Given:
120% of x is equal to 78
We need to write an equation that shows the relationship of 120%, x, and 78
Solution:
We can write the 120% of x as:
⇒ 120% of x
Substitute [tex]\frac{120}{100}[/tex] in the place of 120%.
⇒ [tex]\frac{120}{100}\times x[/tex]
So, we write the equation as:
[tex]\frac{120}{100}\times x=78[/tex]
120 and 100 divided by 10.
[tex]\frac{12}{10}x=78[/tex]
Applying cross multiplication rule.
[tex]12x=780[/tex]
Therefore, equation shows the relationship of 120%, x, and 78.
[tex]\frac{120}{100}\times x=78[/tex] or [tex]12x=780[/tex]
