Explanation:

5)

Step1: Set up ratio

Let $x$ be number of bunches. $\frac{1}{2}=\frac{x}{6}$

Step2: Cross - multiply and solve

$2x = 6$, so $x = 3$

6)

Step1: Set up proportion

Let $h$ be height. $\frac{20}{5}=\frac{h}{1}$, so $h = 4$

11)

Step1: Use exchange rate

If $1$ dollar = $8$ Bolivianos, for $3$ dollars, we have $3\times8=24$ Bolivianos

12)

Step1: Set up proportion

Let $h$ be height. $\frac{2}{3}=\frac{h}{15}$, so $h = 10$

13)

Step1: Set up proportion

Let $h$ be height. $\frac{6}{8}=\frac{h}{4}$, so $h = 3$

19)

Step1: Use exchange rate

If $7$ Rand = $1$ dollar, for $21$ Rand, $\frac{21}{7}=3$ dollars

Answer:

1. 3 bunches
2. 4 in
3. 24 Bolivianos
4. 10 in
5. 3 in
6. 3 dollars
