According to the chart above, the income of Beta Corporation in 2000 was what fraction of Alpha Corporation’s income in 2004?

A. 0.88 / 13

B. 1.74 / 13

C. 2 / 7

D. 2 / 5.8

E. 2.9 / 0.87

(D) As shown in the chart, Beta Corporation's 2004 income is $1.74 billion. The chart shows that this is a 13%

**decrease** from Beta’s income in 2000.

To solve for Beta Corporation's income in 2000, set the 2000 value as

*n*, and set up the following equation:

(100% – 13%)

*n* = $1.74 billion

.87

*n* = $1.74 billion.

Divide both sides by 0.87 to get

*n* = $2 billion.

The question asks what percent of Alpha Corporation's 2004 income was Beta Corporation's 2000 income, namely: 2/5.8. Algebraically, this is 2 =

*x*(5.8).

*x* = 2/5.8. The correct answer is choice (D).

Is there an easy wasy to divide by decimals? I approached this question correctly but made an error in the math of muliplying 0.87 by 1.74.
