Question

#15-4: Aasha completed 1/2 of her science project in 1/4 of a day. At this rate, how long did it take her to complete the entire project?

Answer 1

$\huge{\boxed{\frac{1}{2}\ \text{of a day}}}$

$1 \div \frac{1}{2} = 2$, so there are two halves in one whole. This means we can just multiply $\frac{1}{4}$ by two to find how much of a day Aasha spent on her science project.

$\frac{1}{4} * \frac{2}{1} = \frac{2}{4}$

Divide both the numerator and the denominator by $2$ to simplify the answer.

$\frac{2 \div 2}{4 \div 2} = \boxed{\frac{1}{2}}$
