Ramundus spends 3/7 of his salary on games and 4/9 of his salary on expenses for a car. Does Ramundus spend more of his salary on games or on expenses for a car?
Hello! We need to find a denominator that both fractions can be. /63 works perfectly because 7x9 = 63. 3 x 9 = 27, and 4 x 7 = 28. Since 28/63 is bigger than 27/63, ramundus puts more money into car expenses.
