Practice questions
Challenge questions
Mixed fractions to percentages — some need rounding, some compare two fractions
Word problems
Real-life contexts — read carefully and identify the calculation needed
Two methods
Method 1 — Equivalent fraction over 100:
\(\dfrac{2}{25}=\dfrac{2\times4}{25\times4}=\dfrac{8}{100}=8\%\)
Works when 100 is divisible by the denominator (denominators: 2, 4, 5, 10, 20, 25, 50).
Method 2 — Calculator: divide numerator by denominator, then multiply by 100.
\(\dfrac{7}{16}\): \(7\div16=0.4375\) → \(0.4375\times100=43.75\%\)
