Question

$\frac{7}{2}\text{kg of flour is used to prepare 4 cakes. The}\text{amount of flour used for each cake can be}\text{calculated using :}$

• A. equation C
• B. equation D
• C. equation B
• D. equation A

Answer 1

The correct option is D equation A


$=\frac{7}{2}\text{kg}÷4$

$\text{Calculating}\frac{7}{2}\text{kg}÷4,\text{using the}keep-change-flip\text{method, we get:}$


$\text{Calculating}\frac{7}{2}\times \frac{1}{4}\text{, we get:}$

$\frac{7}{2}\times \frac{1}{4}=\frac{7\times 1}{2\times 4}=\frac{7}{8}$

$\therefore \text{The amoount of flour used for each}\text{cake is}\frac{7}{8}\text{kg and the correct equation}\text{calculating it is:}$

$EquationA:\frac{7}{2}÷4=\frac{7}{8}$
