Hey there!
Let’s leave number unknown.. so we label it as a “e” for equivalent
NEW EQUATION: 5/10 = e/10
FIRST: you have to CROSS MULTIPLY your given values
5 • 10 = e • 2
5 • 10 = 50
e • 2 = 2e
NEW EQUATION: 2e = 50
SECOND: DIVIDE BOTH of the SIDES by 2
2e/2 = 50/2
Cancel out: 2/2 because that gives you 1
Keep: 50/2 because it helps us solve for e
e = 50/2
= 50/2
= 25
Answer: e = 25 ✅
Overall answer for your given equation: 25/10 ☑️
Good luck on your assignment and enjoy your day!
