Martha lived the first one-quarter of her life unmarried, the next one-half of her life in her first marriage, the next one-sixth of her life in her second marriage, and her final 8 years as a widow.
how old was she when she died?
:
Let a = her age when she died
:
Write a equation for each statement
:
"Martha lived the first one-quarter of her life unmarried,
a = unmarried yrs
:
the next one-half of her life in her first marriage,
a = her first marriage yrs
:
the next one-sixth of her life in her second marriage,
a = 2nd marriage yrs
:
and her final 8 years as a widow.
a = a + a + a + 8
common denominator is 12
a = a + + a + 8
a = a + 8
a - a = 8
a = 8
a = 12 * 8
a = 96 yrs
