Same number of marbles used. So this is a 'equal concept' question.
Make all the numerators the same, then compare the denominators.
½ , 3/10, and ¾
Common multiple for the numerator is 3.
Multiply both top and bottom by 3,
½ = 3/6
Comparing the denominator,
John has 6 units
Ming Eng has 10 units
Ahmad has 4 units
Total = 6 + 10 + 4 = 20 units
20 units = 1600
1 unit = 1600 ÷ 20 = 80
They used 3 units each.
Marbles used to fill the box
= 3 × 3 units
= 9 units
= 9 × 80
= 720 (Answer)
