Question

a. $2a = 4.6$ 1. $\frac{8}{5}$
b. $b + 2 = 4.6$ 2. $1\frac{5}{8}$
c. $c \div 2 = 4.6$ 3. $2.3$
d. $d - 2 = 4.6$ 4. $2.6$
e. $x + \frac{3}{8} = 2$ 5. $6.6$
f. $\frac{1}{8}f = 3$ 6. $9.2$
g. $g \div \frac{8}{5} = 1$ 7. $24$

Explanation:

Step1: Solve for $a$

Divide both sides by 2:
$a = \frac{4.6}{2} = 2.3$

Step2: Solve for $b$

Subtract 2 from both sides:
$b = 4.6 - 2 = 2.6$

Step3: Solve for $c$

Multiply both sides by 2:
$c = 4.6 \times 2 = 9.2$

Step4: Solve for $d$

Add 2 to both sides:
$d = 4.6 + 2 = 6.6$

Step5: Solve for $x$

Subtract $\frac{3}{8}$ from 2:
$x = 2 - \frac{3}{8} = \frac{16}{8} - \frac{3}{8} = \frac{13}{8} = 1\frac{5}{8}$

Step6: Solve for $f$

Multiply both sides by 8:
$f = 3 \times 8 = 24$

Step7: Solve for $g$

Multiply both sides by $\frac{8}{5}$:
$g = 1 \times \frac{8}{5} = \frac{8}{5}$

Answer:

A. $2a=4.6$ → 3. 2.3
B. $b+2=4.6$ → 4. 2.6
C. $c÷2=4.6$ → 6. 9.2
D. $d-2=4.6$ → 5. 6.6
E. $x+\frac{3}{8}=2$ → 2. $1\frac{5}{8}$
F. $\frac{1}{8}f=3$ → 7. 24
G. $g÷\frac{8}{5}=1$ → 1. $\frac{8}{5}$
