A baker has 12.5 kg of flour. She uses 3.75 kg for cakes and 4(2/3)kg for bread. How much flour is left?
Show answer & explanation
Correct answer: A
Explanation
Total flour = 12.5 = 25/2
Flour for cake = 3.75 = 15/4
Flour for bread = 4 2/3 = 14/3
Total flour used = 15/4 + 14/3
= 45/12 + 56/12
= 101/12
Remaining flour = 25/2 - 101/12
= 150/12 - 101/12
= 49/12
= 4.08 kg
