Question

In a box of marbles, 25% are blue, 35% are red and the rest are yellow. If there are 112 yellow marbles in the box, how many red marbles are there?

please tell me the whole process, thank you

Answer 1

98 red marbles

Explanation:

112 yellow marbles is 40% of total. If we divide 112 by 5 then that is 5% of total, which is 14. Since the red marbles is 35% of total we can multiply 14(which is 5% of total) and 7, which gives the answer of 98.
