Answer :
Answer:
5 bags of cement are required.
Step-by-step explanation:
Since to make concrete, the ratio of cement to sand is 1: 3, if cement and sand are sold in bags of equal mass, to determine how many bags of cement are required to make concrete using 15 bags of sand the following calculation must be done:
Cement = 1
Sand = 3
3 = 15
1 = X
15/3 = X
5 = X
Therefore, 5 bags of cement are required.
We require 5 bags of cement.
To determine how many bags of cement are needed to make concrete using 15 bags of sand with a ratio of 1:3 for cement to sand, we follow these steps:
Understand the ratio, which means for every 1 bag of cement, there are 3 bags of sand.
To maintain this ratio, the number of cement bags must be one-third the number of sand bags.
Since there are 15 sand bags, we divide this by 3 to find the number of cement bags required: 15 bags of sand ÷ 3 = 5 bags of cement.
Therefore, to create concrete with the 1:3 cement-to-sand ratio, using 15 bags of sand, we require 5 bags of cement.
