Answer:

$\frac{9}{5}$

Step-by-step explanation:

$\frac{4}{9}$ × $\frac{45}{36}$

= $\frac{4}{9}$ × $\frac{5}{4}$ ( cancel 4 on numerator/ denominator )

$\frac{5}{9}$

Given a number n then its reciprocal is $\frac{1}{n}$

Then the reciprocal of $\frac{5}{9}$ is

$\frac{1}{\frac{5}{9} }$ = $\frac{9}{5}$

Answer:

20909.09 grams

Step-by-step explanation:

$\frac{46 \: lb}{1} \times \frac{1 \: kg}{2.2 \: lb} \times \frac{1000 \: g}{1 \: kg} = \\ \frac{46 \: lb}{2.2 \: lb} \times \frac{1 \: kg}{1} \: \times \frac{1000 \: g}{1 \: kg} = \\\frac{230 \: }{11 \:} \times \frac{1 \: kg}{1 \: kg \:}\times \frac{1000 \: g}{1 \:} = \\\frac{230 \: }{11 \:} \times \frac{1}{1}\times \frac{1000 \: g}{1 \:} = \\\ \frac{230}{11}g \times 1g \times \: 1000g$

= 230 grams / 11 grams × 1000 grams = 20.90909... × 1000 = 20909.09 grams
