Zorluk: OrtaFractions, Decimals, and Percentages

A technology firm allocated its annual equipment budget among three divisions. The engineering division received 38\frac{3}{8} of the total budget, and the operations division received 30%30\% of the total budget. The remaining $52,000\$52,000 was allocated to the design division. What was the total equipment budget, in dollars, for the technology firm?

Cevap: 160000 dollars

Cevap

The total equipment budget for the technology firm was $160,000 dollars.
Converting both allocated parts into decimals gives 38=0.375\frac{3}{8} = 0.375 for engineering and 30%=0.3030\% = 0.30 for operations. Combined, these two divisions account for 0.375+0.30=0.6750.375 + 0.30 = 0.675 (or 67.5%67.5\%) of the total budget. The remaining fraction for the design division is 10.675=0.3251 - 0.675 = 0.325 (or 32.5%32.5\%). Dividing the design budget of $52,000\$52,000 by 0.3250.325 yields the total budget of $160,000\$160,000.

Adım Adım Çözüm

1
Convert the percentage and fraction to equivalent decimal values.
Engineering receives 38=0.375\frac{3}{8} = 0.375, and operations receives 30%=0.3030\% = 0.30.
Expressing all portions in decimal form allows for straightforward addition and subtraction.
2
Sum the portions allocated to the engineering and operations divisions.
0.375+0.30=0.6750.375 + 0.30 = 0.675.
This finds the total proportion of the budget that has already been accounted for.
3
Determine the remaining decimal portion allocated to the design division.
10.675=0.3251 - 0.675 = 0.325.
The complete budget represents 1 whole (100%). Subtracting the allocated portions yields the design division's share.
4
Divide the dollar amount of the design division by its decimal portion to calculate the total budget.
52,0000.325=160,000\frac{52,000}{0.325} = 160,000.
Since Design Portion×Total Budget=Design Amount\text{Design Portion} \times \text{Total Budget} = \text{Design Amount}, dividing the amount by the decimal portion gives the total budget.
