Question

2/5+3/5+11/2
Answer is 24/20 but I want to know how we can do... don't answer ​

Answer 1

Answer:

13/2

Step-by-step explanation:

Take the lcm of denominator

Lcm of 5,5,2 = 10

So we can write as

4/10+6/10+55/10

=65/10

=13/2

Answer 2

The answer is $6\:\frac{1}{2}$

$\frac{2}{5}+\frac{3}{5}+\frac{11}{2}=6\frac{1}{2}$

$Multiplying\:numerators\:and\:denominators$ $to\:get\:the\:LCD\:in\:all\:fraction\:denominators$

$=\frac{2\times \:2}{5\times \:2}+\frac{3\times \:2}{5\times \:2}+\frac{11\times \:5}{2\times \:5}$

$Then\:rewriting\:the\:equation\:with\:the\:equivalent\:fractions$

$=\frac{4}{10}+\frac{6}{10}+\frac{55}{10}$

$With\:like\:denominators\:we\:can\:operate\:on\:just\:the\:numerators$

$=\frac{4+6+55}{10}$

$=\frac{65}{10}$

$Simplify\:the\:answer$

$\frac{65}{10}=6\:\frac{1}{2}$
