\implies {\blue {\boxed {\boxed {\purple {\sf {Numerator\:=\:25  }}}}}}

\implies {\blue {\boxed {\boxed {\purple {\sf {Denominator \:=\:56}}}}}}

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}

\:  \frac{ - 3}{7}  +  \frac{7}{8}

Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.

The L. C. M for 7 and 8 is 56.

Now,

➺\:  \frac{ - 3 \times 8}{7 \times 8}  +  \frac{7 \times 7}{8 \times 7}

➺\:   \frac{ - 24}{56}  +  \frac{49}{56}

Now that the denominators are equal, we can add them.

➺\:  \frac{ - 24 + 49}{56}

➺\:  \frac{ 25}{56}

Therefore, the numerator is \boxed{ 25 } and the denominator is \boxed{ 56 }.

\large\mathfrak{{\pmb{\underline{\orange{Mystique35 }}{\orange{ヅ}}}}}

Sonja has $1,800 to invest, And she has a choice between two savings accounts. Saving account a offers an interest rate of 3.6%
son4ous [18]

Answer:

$46.83

Step-by-step explanation:

The standard formula for compound interest is given as;

A = P(1+r/n)^(nt) .....1

Where;

A = final amount/value

P = initial amount/value (principal)

r = rate yearly

n = number of times compounded yearly.

t = time of investment in years

For saving account A;

P = $1,800

t = 2 years

n = 12 (monthly

r = 3.6% = 0.036

Substituting the values;

A = 1800(1+0.036/12)^(12×2)

A1 = $1934.17

for saving account B;

P = $1,800

t = 2 years

n = 12 (monthly

r = 4.8% = 0.048

Substituting the values;

A = 1800(1+0.048/12)^(12×2)

A2 = $1981.00

The difference will then be

d = A2 - A1

d = $1981.00 - $1934.17

d = $46.83

Therefore, she would have $46.83 more
