The number is 30.
Step-by-step explanation:
n=number.
2/3n+1/6n=25
Make a common denominator for 2/3 and 1/6 and then combine like terms.
4/6n+1/6n=25
5/6n=25
divide 5/6 on both sides to isolate n.
n=25/(5/6)
oreja.
n=25/1/5/6
nu(25×6)/(5×1)
n=150/5
n=30
OR
multiply the reciprocal instead of dividing.
n=25×(6/5)
n=150/5
n=30
