Question

Round the answer to 1 decimal digit.
a/6 = 5/7 help me!!

Answer 1

The answer is: a = 4.3 .
____________________________________
Step-by-step explanation:
____________________________________
Given:
____________________________________
a/6 = 5/7 ; Solve for "a" ;
____________________________________

7a = 5*6 ;

7a = 30 ;

Divide EACH side of the equation by "7" ; to isolate "a" on one side of the equation; and to solve for "a" ;
___________________________________
7a / 7 = 30 / 7 ;
____________________________________
a = 30 / 7 = 4.2857142857142857 ;

→ round to 1 decimal digit ;

→ The first 2 decimal digits are: 4.28 ;
Since the 2nd decimal digit is "8" (i.e., "5" or greater),
we round the first decimal digit to the higher number;

→ The answer is: a = 4.3 .
