Question

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 1

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 $\frac{3}{10}$ = $\frac{43}{10}$ gallons

The quantity of blue paint = 3 $\frac{2}{5}$ = $\frac{17}{5}$ gallons

So, The total quantity of paints = The quantity of red paint + The quantity of blue paint

or, The total quantity of paints =  $\frac{43}{10}$ +  $\frac{17}{5}$

Or, The total quantity of paints = $\frac{43+34}{10}$

Or,  The total quantity of paints = $\frac{77}{10}$ = 7.7 gallons

Now, The total number of bookshelves to be paint = 7

And  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 = $\frac{7.7}{7}$ gallons

I.e To paint the 7 bookshelves , the quantity of paints = 1.1 gallons

Hence The quantity of paints did Brain uses to paint each bookshelves is 1.1 gallons . Answer
