Given that A box contains oranges and bananas. If the ratio of the number of oranges to bananas is 3:5 and the number of oranges is 21.
Let number of oranges be 3x and number of Bananas be 5x
We have to calculate the number of bananas. since it's given that the number of oranges are 21 i.e,
[tex]\sf 3x = 21 [/tex]
To solve for x, divide both sides by 3:
[tex]\bf x = 7[/tex]
Now, number of bananas are 5x
To Calculate the number of bananas, substitute the value of x,
Number of bananas = 5(7)
Number of bananas = 35
Therefore, the number of bananas are 35.
