  1. The number of roses left after 50 of them are sold will be 450 roses.

    What are ratios and proportions?

    An ordered pair of numbers, a and b, is referred to as a ratio when b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
    It is given that R: S: T is 5: 6: 9 <- before selling 50 R and after 50 roses are sold the ratio is 3: 4: 6 <- after selling 50 R.
    Find the remaining number of R.
    9 / 6 = 1,5
    6 / 4 = 1,5
    3 × 1,5 = 4,5
    Let the number of roses before sold be n then the number of roses left will be calculated as below:-
    5/4,5 = n/n-50
    50/45 = 10n/(10(n-50))
    450n = 500(n-50)
    450n = 500n – 2500
    (500-450)n = 2500
    50n = 2500
    n = 2500/50
    n = 500 roses
    500 – 50 roses = 450 roses
    Therefore, the number of roses left after 50 of them are sold will be 450 roses.
