Readers' methods

Colin T, Fareham PO17:
1/8 of 1/9 is 1/72.
1/9 is 8/72.
8/72 plus 1/72 is 9/72, which is the same as 1/8.

Joan, msn:
a ninth plus an eighth of a ninth,
that's one and one eighth of a ninth,
which is nine eighths of a ninth,
which is 9/8 x 1/9 which cancels to give 1/8.

JM Greeves, Bath BA2:
1 x 1/9 plus 1/8 x 1/9 is the same as 1 1/8 x 1/9
whixch is equal to 9/8 x 1/9 = 1/8.

Pupils from Holgate Comprehensive School, Hucknall, Nottinghamshire:
1/9 + (1/8 x 1/9) = 8/72 + 1/72 = 9/72 = 1/8
