Question

Anu had 45.5g of butter, but found that she needed 60g of butter for her recipe. How much more butter does Anu need. Express the answer in kilograms.

• A. 0.0145 kg
• B. 0.145kg
• C. 1.45kg
• D. 0.00145kg

Answer 1

The correct option is A 0.0145 kg

Amount of butter with Anu = 45.5g
Amount of butter needed for Anu's recipe = 60g
Hence, Anu needs (60-45.5)g of more butter
60 - 45.5 = 14.5g
1000g = 1kg $\therefore$ 1g = $\frac{1}{1000}$kg
$\Rightarrow$ 14.5g = $\frac{14.5}{1000}$ = 0.0145kg
