Answer:
580
Step-by-step explanation:
Let's translate this word for word.
87 is 15% of what number
87 = 15% times x
87=.15 times x
[tex]87=.15 \cdot x[/tex]
Divide both sides by .15
[tex]\frac{87}{.15}=\frac{.15x}{.15}[/tex]
Cancel out the common factor of .15 on the right; that is .15/.15=1.
[tex]580=x[/tex]
580 is the number
Answer:
580
Step-by-step explanation:
Alright. Translate that into math, and you get:
87=15/100x
multiply both sides by x
8700/15=x
x=8700/15
x=580
Check:
580*15/100
58*15/10
870/10
87
BINGO!
