fractions communicate ie 1/4 * 1/2 * 1/5 = 1/2 *1/4 * 1/5 etcso use 200 * 1/(2*4*5) or 200/40 = 5
2008-06-05 10:12 am
= 200(1/4)(1/2)(1/5)
= (200/[4 *2 * 5])(1/[4/4])(1/[2/2])(1/[5/5])
= (200/40)(1/1)(1/1)(1/1)
= 5
= (200/[4 *2 * 5])(1/[4/4])(1/[2/2])(1/[5/5])
= (200/40)(1/1)(1/1)(1/1)
= 5

1/40 x 200 = 5
2 - 90 = - 88
2 - 90 = - 88

200 x 1/5 x 1/2 x 1/4
= 200/5 x 1/2 x 1/4
= 40 x 1/2 x 1/4
= 40/2 x 1/4
= 20 x 1/4
= 20/4
= 5
= 200/5 x 1/2 x 1/4
= 40 x 1/2 x 1/4
= 40/2 x 1/4
= 20 x 1/4
= 20/4
= 5

In general, "of" means to multiply.
So you have 1/4 x 1/2 x 1/5 x 200, which is 5.
So you have 1/4 x 1/2 x 1/5 x 200, which is 5.
