Question

What is 4 3/4 + 7/8 showing all work

Answer 1

$4 \frac{3}{4} + \frac{7}{8}$

Convert  mixed numbers  to improper fractions

$= \frac{19}{4} + \frac{7}{8}$

Find de LCD  for 4 and 8 :

Factor each denominator  into its primes:

$4 = 2^2$

$8 = 2^3$

Find the  least common denominator $2^3 = 8$

Adjust  fractions  based on  the LCD :

$\frac{19*2}{8} + \frac{7}{8}$

Since the  denominators are equal , combine the fractions:

$\frac{2*19+7}{8}$

$\frac{38+7}{8}$

$= \frac{45}{8}$

Therefore:

Convert  improper fractions to mixed numbers

$= 5 \frac{5}{8}$

hope this helps!
