Question

find the value of X when 2.5:4=x:7.5 but make sure that the answer will be 4 whole 11/16​

Answer 1

Answer:

75/16 OR 4 whole 11/16

Step-by-step explanation:

Remember,

2.5 = 25/10 = 5/2

7.5 = 75/10 = 15/2

=> 2.5 : 4 = x : 7.5

=> 4x = 2.5×7.5 [product of means=product of extremes]

=> 4x = (5/2)(15/2)

=> 4x = 75/4

=> x = (75/4) ÷ 4

=> x = 75/4 × 1/4

=> x = 75/16

=> x = 4 whole 11/16
