4 bags of cement do 18 m² how many m^2 can be done with seven bags
nikitadnepr [17]

Answer:

31.5 m^2

Step-by-step explanation:

To find the amount for 7 bags, create a proportion.

\frac{4}{18} =\frac{7}{y}

To solve for y, cross multiply numerator to denominator of each fraction.

4(y) = 18(7)

4y= 126

y= 31.5

7 bags will do 31.5 m^2
