Let's solve each part of the problem step-by-step. --- ### **a. Express Kulani and Bolani's Weekly Pocket Money as a Ratio** - **Kulani's weekly pocket money** = R70 - **Bolani's weekly pocket money** = R42 **Ratio** = Kulani's pocket money : Bolani's pocket money = 70 : 42 **Simplifying the Ratio:** - Divide both numbers by their greatest common divisor (GCD), which is 14. = (70 ÷ 14) : (42 ÷ 14) = **5 : 3** --- ### **b. Express Kulani's Weekly Savings as a Fraction of His Weekly Pocket Money** - **Kulani's weekly savings** = R21 - **Kulani's weekly pocket money** = R70 **Fraction** = Savings / Pocket Money = 21 / 70 **Simplifying the Fraction:** - Divide numerator and denominator by 7. = (21 ÷ 7) / (70 ÷ 7) = **3/10** So, Kulani saves **3/10** of his weekly pocket money. --- ### **c. Express Bolani's Weekly Savings as a Fraction of His Weekly Pocket Money** - **Bolani's weekly savings** = R14 - **Bolani's weekly pocket money** = R42 **Fraction** = Savings / Pocket Money = 14 / 42 **Simplifying the Fraction:** - Divide numerator and denominator by 14. = (14 ÷ 14) / (42 ÷ 14) = **1/3** So, Bolani saves **1/3** of his weekly pocket money. --- ### **d. Calculate the Total Savings of Each Boy in a Month of Four Weeks** - **Kulani's weekly savings** = R21 **Total monthly savings** = 21 × 4 = **R84** - **Bolani's weekly savings** = R14 **Total monthly savings** = 14 × 4 = **R56** --- ### **e.
