1. $\frac{1}{2}\times10 =$

1. $24\times\frac{3}{8} =$

1. a group of 18 friends is going to a

only $\frac{1}{3}$ of them have been to a the
how many members of the group
park before? solve the problem a

Explanation:

Step1: Calculate \(\frac{1}{2}\times10\)

Multiply the numerator \(1\) by \(10\) and keep the denominator \(2\), so \(\frac{1\times10}{2}\).

Step2: Simplify the fraction

\(\frac{10}{2} = 5\).

Step3: Calculate \(24\times\frac{3}{8}\)

Multiply \(24\) by \(3\) to get \(72\), then divide by \(8\), so \(\frac{24\times3}{8}=\frac{72}{8}\).

Step4: Simplify the fraction

\(\frac{72}{8}=9\).

Step5: Solve the word - problem

We need to find \(\frac{1}{3}\) of \(18\). Using the formula \(a\times\frac{b}{c}\), here \(a = 18\), \(b = 1\), \(c = 3\). So \(\frac{18\times1}{3}\).

Step6: Simplify the fraction

\(\frac{18}{3}=6\).

Answer:

1. \(5\)
2. \(9\)
3. \(6\)
