Answer:

a=60

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.18a+8.4=0.32a

Step 2: Subtract 0.32a from both sides.

0.18a+8.4−0.32a=0.32a−0.32a

−0.14a+8.4=0

Step 3: Subtract 8.4 from both sides.

−0.14a+8.4−8.4=0−8.4

−0.14a=−8.4

Step 4: Divide both sides by -0.14.

−0.14a ÷ −0.14 = −8.4 ÷ −0.14

a=60

Complete the steps 4/9 divided by 1/2

DedPeter [7]

Answer: 0.88 (the 8 recurs)

Step-by-step explanation:

$\frac{4}{9}$ ÷ $\frac{1}{2}$

$\frac{4}{9}$ × $\frac{2}{1}$ (Then the the fraction should reciprocal so the values should shift to the opposite side were 2 goes up and 1 goes down and the sign turns to the multiplication sign)

then u should multiply the two fractions which gives 8/9

next you should divide 8 by 9 which gives 0.88(the number eight is recurring which means that the number 8 keeps repeating no matter how many times you try to divide)
