Answer:
The value of variable a is 12.5.
Step-by-step explanation:
4 is to 5 as 10 is to a.
or, 4 : 5 = 10 : a
By the RATIO OF PROPORTIONALITY:
or, the value of a = 12. 5
⇒ 4 is to 5 as 10 is to 12.5
Hence, the value of variable a is 12.5.
x=12.5
4/5=10/x
cross product
5*10=4*x
50=4x
x=50/4
simplify,
x=25/2
a=24 0.5x24=12
