First, deduct 15% from the total weight of 2400kg because that is water. That leaves you with 2040kg total weight. So the combined weight of cement, sand, and stone gives you 2040kg in a 1:2:5 ratio.
A 1:2:5 ratio is the equivalent of being out of parts of 8. So the amount of cement is 1 part out of 8 (1/8), sand is 2 out of 8 (2/8), and stone is 5 out of 8 (5/8).
Amount of cement is one-eighths of 2040kg so (1/8) * (2040) = 255kg Amount of sand is two-eighths of 2040kg so (2/8) * (2040) = 510kg Amount of stone is five-eighths of 2040kg so (5/8) * (2040) = 1275kg
800 flyersOn Earth day, a local community wants to distribute 800 flyers, 300 banners, and 250 badges to volunteers in packets containing the three items. What is the greatest number of packets that can be made using all these items if each type of item is equally distributed among the packets?
