1 Simplify \frac{4}{15}x

15

4

x to \frac{4x}{15}

15

4x \frac{4x}{15}=1.44

4x =1.44

2 Multiply both sides by 1515.

4x=1.44\times 15

4x=1.44×15

3 Simplify 1.44\times 151.44×15 to 21.621.6.

4x=21.6

4x=21.6

4 Divide both sides by 44.

x=\frac{21.6}{4}

x= 4

21.65 Simplify \frac{21.6}{4} 421.6 to 5.45.4.

x=5.4

x=5.4

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
