Question

1. spent $\frac{1}{6}$ of an hour making minutes
2. circle the fraction if it is equivalent to $\frac{2}{3}$. $\frac{2}{3}$ $\frac{3}{4}$ $\frac{4}{8}$ $\frac{4}{9}$ $\frac{6}{9}$ $\frac{8}{12}$ $\frac{4}{6}$ $\frac{8}{10}$ $\frac{2}{6}$ write another fraction equivalent to $\frac{2}{3}\to$
3. $\

$$\begin{array}{r}5,392 \\\\ \\times 58 \\\\ \\hline\\end{array}$$

$ $\

$$\begin{array}{r}435 \\\\ \\times 67 \\\\ \\hline\\end{array}$$

1. ◆ round it ◆ round each decimal to the nearest whole number and tenth.
2. just the facts how fast can you solve? $\frac{64}{\div \square}$ $\frac{32}{\div \square}$ $\frac{42}{\div \square}$ $\frac{54}{\div \square}$ $\frac{48}{\div \square}$ $\frac{72}{\div \square}$ $\frac{25}{\div \square}$ $\frac{36}{\div \square}$ $\frac{27}{\div \square}$ $\frac{56}{\div \square}$

Explanation:

Step1: Simplify the fractions

• For \(\frac{4}{8}\), simplify by dividing numerator and denominator by \(4\), we get \(\frac{1}{2}\).
• For \(\frac{6}{9}\), divide numerator and denominator by \(3\), we get \(\frac{2}{3}\).
• For \(\frac{8}{12}\), divide numerator and denominator by \(4\), we get \(\frac{2}{3}\).
• For \(\frac{4}{6}\), divide numerator and denominator by \(2\), we get \(\frac{2}{3}\).
• \(\frac{3}{4}\) and \(\frac{4}{9}\) and \(\frac{8}{10}\) and \(\frac{2}{6}\) do not simplify to \(\frac{2}{3}\).

Step2: Find another equivalent fraction

Multiply numerator and denominator of \(\frac{2}{3}\) by \(4\), we get \(\frac{8}{12}\) (already in the list, another example: multiply by \(5\) gives \(\frac{10}{15}\)).

For rounding:

• For \(64.53\):
• To the nearest whole number: Look at the tenths place (\(5\)), so \(64.53\approx65\).
• To the nearest tenth: Look at the hundredths place (\(3\)), so \(64.53\approx64.5\).
• For \(934.29\):
• To the nearest whole number: Look at the tenths place (\(2\)), so \(934.29\approx934\).
• To the nearest tenth: Look at the hundredths place (\(9\)), so \(934.29\approx934.3\).
• For \(5.634\):
• To the nearest whole number: Look at the tenths place (\(6\)), so \(5.634\approx6\).
• To the nearest tenth: Look at the hundredths place (\(3\)), so \(5.634\approx5.6\).

For \(5\) (Just the Facts):

• \(64\div8 = 8\).
• \(32\div4 = 8\).
• \(42\div7 = 6\).
• \(54\div6 = 9\).
• \(48\div8 = 6\).
• \(72\div9 = 8\).
• \(25\div5 = 5\).
• \(36\div4 = 9\).
• \(27\div9 = 3\).
• \(56\div7 = 8\).

Answer:

• For equivalent fractions: Circle \(\frac{6}{9}\), \(\frac{8}{12}\), \(\frac{4}{6}\). Another equivalent fraction: \(\frac{10}{15}\) (for example).
• Rounding:
• \(64.53\): Nearest whole number \(65\), nearest tenth \(64.5\).
• \(934.29\): Nearest whole number \(934\), nearest tenth \(934.3\).
• \(5.634\): Nearest whole number \(6\), nearest tenth \(5.6\).
• Just the Facts: \(8\), \(8\), \(6\), \(9\), \(6\), \(8\), \(5\), \(9\), \(3\), \(8\).
