Question

$\text{A melon weighs}\frac{28}{3}\text{kg. If it is divided into 7 equal}\text{parts, the weight of each part is given by:}$

• A. Equation C
• B. Equation D
• C. Equation A
• D. Equation B

Answer 1

The correct option is D Equation B

$\text{Weight of the whole melon}=\frac{28}{3}\text{kg}$

$\text{Number of equal parts of the melon}=7$

$⟹\text{Weight of each part of the melon}=\frac{28}{3}\text{kg}÷7$

$\text{Calculating}\frac{28}{3}÷7\text{using the}keep-change-flip\text{method, we get}:$


$\text{Calculating}\frac{28}{3}\times \frac{1}{7}\text{, we get:}$

$\frac{28}{3}\times \frac{1}{7}=\frac{28\times 1}{3\times 7}=\frac{28}{21}=\frac{4}{3}$

$⟹\text{Weight of each part of the melon}=\frac{4}{3}\text{kg}$

$\therefore \text{The weight of each part of the melon}$ $\text{is given by:}$

$EquationB:\frac{28}{3}÷7=\frac{4}{3}$
