• C. 5.38 Grams
• D. $\frac{675}{1000}\text{Kg}$

Answer 1

Answer: (A), (B)

$\frac{269}{50}\text{Kg}$

Amount of rice jenny bought = 6.72 Kg
Amount of rice jenny used to make rice ball = 1340 Grams

We know: To convert grams into Kilograms, we need to divide quantity in grams by 1000.

$1340\text{g}=\frac{1340}{1000}\text{Kg}=1.34\text{Kg}$

Amount of rice left $=(6.72-1.34)\text{Kg}$
$=5.38\text{Kg}$

Converting it into fraction we get,
$5.38\text{Kg}=\frac{538}{100}\text{Kg}$

On furthur simplifying
$5.38\text{Kg}=\frac{538}{100}\text{Kg}=\frac{269}{50}\text{Kg}$
