Ok so put the a factors together first
4a + 19 - 3a - 7 = a + 19 + 7
a + 19 + 7 = a + 26
(-2/3) / (5/4) =
-2/3 * 4/5 =
-8/15 <=
Therefore, the decimal equivalent to the expression
is 50.02
The given expression is:

Note that 
The expression therefore becomes:
(5 x 10) + (2 x 0.01)
50 + 0.02
= 50.02
Therefore, the decimal equivalent to the expression
is 50.02
