- \( 40\% \) of 120 cm is **48 cm**.
- \( 15\% \) of \( 360^{\circ} \) is **54 degrees**.
- \( 66 \frac{2}{3}\% \) of 54 seconds is **36 seconds**.
Solución
Sure, let's solve each part step by step.
### Problem 6
**Find the value of each of the following:**
#### (a) \( 40\% \) of 120 cm
**Solution:**
To find \( 40\% \) of 120 cm:
1. Convert the percentage to a decimal:
\[
40\% = \frac{40}{100} = 0.40
\]
2. Multiply the decimal by the given value:
\[
0.40 \times 120\, \text{cm} = 48\, \text{cm}
\]
**Answer:** \( 40\% \) of 120 cm is **48 cm**.
#### (b) \( 15\% \) of \( 360^{\circ} \)
**Solution:**
To find \( 15\% \) of \( 360^{\circ} \):
1. Convert the percentage to a decimal:
\[
15\% = \frac{15}{100} = 0.15
\]
2. Multiply the decimal by the given value:
\[
0.15 \times 360^{\circ} = 54^{\circ}
\]
**Answer:** \( 15\% \) of \( 360^{\circ} \) is **54 degrees**.
#### (c) \( 66 \frac{2}{3}\% \) of 54 s
**Solution:**
To find \( 66 \frac{2}{3}\% \) of 54 seconds:
1. Convert the mixed number percentage to an improper fraction or decimal:
\[
66 \frac{2}{3}\% = \frac{200}{3}\% = \frac{200}{3} \times \frac{1}{100} = \frac{2}{3} \approx 0.6667
\]
2. Multiply the decimal or fraction by the given value:
\[
\frac{2}{3} \times 54\, \text{s} = 36\, \text{s}
\]
**Answer:** \( 66 \frac{2}{3}\% \) of 54 seconds is **36 seconds**.

To find \( 40\% \) of \( 120 \) cm, you simply multiply \( 120 \) by \( 0.40 \) (which is \( 40\% \) expressed as a decimal). That gives you \( 48 \) cm. For \( 15\% \) of \( 360^\circ \), convert \( 15\% \) to a decimal (which is \( 0.15 \)) and then multiply: \( 0.15 \times 360 = 54^\circ \). Lastly, to calculate \( 66 \frac{2}{3} \% \) of \( 54 \) s, first convert \( 66 \frac{2}{3} \% \) to decimal form which is \( 0.6667 \) (approximately). Then, multiply \( 54 \) by \( 0.6667 \) to get \( 36 \) s.
