Answer:

1 whole 3/4 or 1.75

Step-by-step explanation:

3 \frac{1}{6} + 1\frac{1}{4} -2\frac{2}{3} = \frac{19}{6} + \frac{5}{4} - \frac{8}{3}

                    = \frac{(19 \times 2) + ( 5 \times 3 ) - (8 \times 4)}{12}\\\\=\frac{38+15-32}{12}\\\\=\frac{21}{12} \\\\=\frac{7}{4}\\\\=1 \frac{3}{4}

Henry wants to paint the ceilings and the walls of his living room. One gallon of paint covers 450 ft squared. The rooms is 24 f
Mamont248 [21]
If you would like to know how many gallons of paint will Henry need to paint his living room, you can calculate this using the following steps:

the ceiling: 24 ft * 18 ft = 432 ft squared
walls: 2 * 24 ft * 9 ft + 2 * 18 ft * 9 ft = 2 * 24 * 9 + 2 * 18 * 9 = 432 + 324 = 756 ft squared

432 ft squared + 756 ft squared = 1188 ft squared

1 gallon of paint ... 450 ft squared
x gallons of paint = ? ... 1188 ft squared

1 * 1188 = 450 * x
1188 = 450 * x    /450
x = 1188 / 450
x = 2.64 gallons of paint

The correct result would be 2.64 gallons of paint.
