1. Problem Description

We have a paint that can cover 712\frac{7}{12} m2m^2 of board with 79\frac{7}{9} dL. We want to find out how much area (in m2m^2) can be covered by 1 dL of the paint.

2. Solution Steps

To find the area covered by 1 dL, we need to divide the area covered by 79\frac{7}{9} dL by 79\frac{7}{9}. This can be expressed as:
Area=712÷79 Area = \frac{7}{12} \div \frac{7}{9}
To divide by a fraction, we multiply by its reciprocal:
Area=712×97 Area = \frac{7}{12} \times \frac{9}{7}
We can simplify before multiplying:
Area=14×31 Area = \frac{1}{4} \times \frac{3}{1}
Area=34 Area = \frac{3}{4}
The equation written on the page is incorrect, instead it should have been:
712÷79=712×97\frac{7}{12} \div \frac{7}{9} = \frac{7}{12} \times \frac{9}{7}
After simplification it yields:
14×31=34\frac{1}{4} \times \frac{3}{1} = \frac{3}{4}
The final answer written on the page is 43\frac{4}{3}, but it should be 34\frac{3}{4}

3. Final Answer

The area that can be covered by 1 dL of paint is 34\frac{3}{4} m2m^2.
