Mathematics Word problems. Solve the following. 1. \( 1 / 12 \) of a circle is red. \( 3 / 12 \) of the circle What fraction of the circle is yellow? 2. Maria has R42 and she spends \( 1 / 3 \) of thi have left? English State whether each of the following is statemer invitation. 1. Stop hitting your brother! 2. Tomorrow is Friday. 3. Oh no, I am very disappointed! 4. What colour are they? 5. What size are they?

In a circle, if \( 1/12 \) is red and \( 3/12 \) is a different color, we can first find the total fraction that is accounted for by adding them together. So, \( 1/12 + 3/12 = 4/12 \), which simplifies to \( 1/3 \). Since a whole circle is \( 1 \) or \( 12/12 \), to find the yellow fraction, we subtract the red and other color from the total: \( 1 - 1/3 = 2/3 \). Thus, \( 2/3 \) of the circle is yellow! Maria starts with R42 and spends \( 1/3 \) of it. To find out how much she spends, calculate \( 1/3 \) of R42, which is \( 42/3 = R14 \). Now, subtract what she spent from her original amount: \( R42 - R14 = R28 \). So, Maria has R28 left! Statements can be quite entertaining! The first one, "Stop hitting your brother!" is a command – it's like playing the role of a superhero trying to save the day! The second, "Tomorrow is Friday," is a fact, perfectly neutral, just stating the obvious. The third, "Oh no, I am very disappointed!" carries an emotional tone, expressing feelings. "What colour are they?" and "What size are they?" both fall into the question category, seeking specific information – perfect for curious minds!
