Question

evaluate a+b when a=5/6 and b=3 1/4

Answer 1

Answer:

4 1/12

Step-by-step explanation:

a = 5/6        b = 3 1/4 = 13/4

To add 5/6 + 13/4, we have to make the denominators the same:

20/24 + 78/24 = 98/24
To make it back to a mixed fraction:

4 2/24
4 1/12

Answer 2

Answer:

$4\frac{1}{12}$

Step-by-step explanation:

Given the following question:

$a+b$
$a=\frac{5}{6}$
$b=3\frac{1}{4}$
$\frac{5}{6} +3\frac{1}{4}$

To find the answer we have to convert the mixed number into an improper fraction, find the common denominator, and then add the numerators.

$\frac{5}{6} +3\frac{1}{4}$
$3\frac{1}{4} =4\times3=12+1=\frac{13}{4}$
$\frac{5}{6} +\frac{13}{4}$
$\frac{5}{6} \times4=\frac{20}{24}$
$\frac{13}{4} \times6=\frac{78}{24}$
$20+78=98$
$\frac{98}{24} \div2=\frac{49}{12}$
$\frac{49}{12} =49\div12=4\frac{1}{12}$
$=4\frac{1}{12}$

Hope this helps.
