A school takes delivery of some boxes of balls. In each bos, there are 5 red balls and 3 blue balls. In the whole delivery, there are 40 red balls. How many balls are there altogether?​



Answer :

Answer:

64 balls

Step-by-step explanation:

The ratio of red balls : blue balls = 5: 3, let the total balls delivered be x and the number of red balls be 40, then

[tex] \frac{5}{8}x = 40[/tex]

[tex]5x = 40 \times 8[/tex]

[tex]x = \frac{40 \times 8}{5} = 64[/tex]

There are 64 balls altogether
