Brian used 4 3/10 gallons of red paint and 3 2/5 gallons of blue to paint 7 bookshelves. How many gallons og paint did he use for each bookshelf​

Answer:The quantity of paints did Brain uses to paint each bookshelves is 1.1 gallons .Step-by-step explanation:Given as :The quantity of red paint = 4 [tex]\frac{3}{10}[/tex] = [tex]\frac{43}{10}[/tex] gallonsThe quantity of blue paint = 3 [tex]\frac{2}{5}[/tex] = [tex]\frac{17}{5}[/tex] gallonsSo, The total quantity of paints = The quantity of red paint + The quantity of blue paintor, The total quantity of paints =  [tex]\frac{43}{10}[/tex] +  [tex]\frac{17}{5}[/tex]Or, The total quantity of paints = [tex]\frac{43+34}{10}[/tex]Or,  The total quantity of paints = [tex]\frac{77}{10}[/tex] = 7.7 gallonsNow, The total number of bookshelves to be paint = 7And  The total quantity of paints = 7.7 gallons∵ To paint the 7 bookshelves , the quantity of paints = 7.7 gallons∴ To paint the 1 bookshelves , the quantity of paints = [tex]\frac{7.7}{7}[/tex] gallonsI.e To paint the 7 bookshelves , the quantity of paints = 1.1 gallonsHence The quantity of paints did Brain uses to paint each bookshelves is 1.1 gallons .
