Zak and Zara share 56 pears in the ratio 3:4. Zak gives 1/4 to another friend. How many does Zak have left

Question

The ratio is 3:4

Answer 1

first, Need to figure out how many pears Zak has before he gives to his friend.  what does 3:4 ratio really mean?  it means that out of 7 pears, zak would have 3 and zara 4.   now 56 pears is 8 groups of 7.  so Zak has 3*8 = 24 pears.  If he gives 1/4 to his friend(24*1/4=6), he's left with 24-6 or 18.
