1. Finding fractions of amounts
By the end of this lesson, you should be able to:
Calculate a fraction of an amount
e.g. two-thirds of fifteen: 2/3 x 15
Find a fraction of a fraction for halves, quarters and eighths
e.g. a quarter of a half (1/4 x 1/2)
or three eighths of a quarter (3/8 x 1/4)

8. Multiply the numerators by each other to find the new numerator
( 3 x 2 = 6 )
Multiply the denominators by each other to find the new denominator
( 4 x 3 = 12 )
( 3/4 of 2/3 = 6/12 = 1/2 )
