Question

Given that 4 ≤ x ≤ 7 and 57 ≤ y ≤ 64, find :
i) the greatest value of y/x

ii) the least value of y/x

.

Answer 1

Step-by-step explanation:

1) for finding the greatest value of y/x

we have to put Maximum value of y and minimum value of x

Maximum value of y = 64

Minimum value of x = 4

so the greatest value of y/x = 64/4 = 16

Hence the greatest value of y/x = 16

2) for finding the least value of y/x

we have to put minimum value of y and maximum value of x

Minimum value of y = 57

Maximum value of x = 7

so the least value of y/x = 57/7

Hence the least value of y/x is 57/7
