Question

Evaluate: 12(1/2)% of 560 km + 66(2/3)% of 240 km.

• A. 140 km
• B. 230 km
• C. 320 km
• D. 450 km

Answer 1

Answer:

B. 230 km

Interpret the percentages:

$12\frac{1}{2}\% = \frac{25}{2}\% = \frac{1}{8}$

$66\frac{2}{3}\% = \frac{200}{3}\% = \frac{2}{3}$

Now calculate:

First part

$\frac{1}{8} \times 560 = 70$

Second part

$\frac{2}{3} \times 240 = 160$

Add them:

$70 + 160 = 230$

Therefore,

$\boxed{230 \text{ km}}$
