**Jai**, Monday, May 21, 2012 at 10:33pmNo. First to multiply fractions, we change mixed number into improper fraction. The mixed number here is 1 1/4. To change this, we multiply the denominator (the 4) to the constant (the first 1, not the 1 above the bar line) and add this to numerator. thus,

1 1/4 = (1*4 + 1)/4 = 5/4

then recall that the area of triangle is given by

A = (1/2)bh

where b is base and h is height

substituting,

A = (1/2) * (5/4) * (4/9)

to multiply fractions, we just multiply the numerator by numerator & denominator by denominator:

A = (1 * 5 * 4) / (2 * 4 * 9)

A = 20/72

A = 5/18

hope this helps~ :)
