Question

a man bought 9/2 kg of Apples 11/4of guavas and 16/5 kg of oranges how many kg of fruits did he buy​

Answer 1

Answer:

10.45 kg

Step-by-step explanation:

take l.c.m. of 2,4,5

l.c.m. = 20

===> 90 + 55 + 64

-----------

20

==> 209

----

20

answer = 10.45

hope it will help you

Answer 2

Solution

How to solve ?

1. We have to add the weight of given fruits.

2. Then their denominator is not same.

3. To make the denominator same, we have to find LCM of denominator.

4. After finding LCM, follow the process which is used to equal denominator.

5. After that add the fraction and you will get your answer.

                                                                             

Now come to your question,

Weight of Apples = $\dfrac{9}{2}$

Weight of Guavas =  $\dfrac{11}{4}$

Weight of Oranges =  $\dfrac{16}{5}$

                                                                                   

We have to find how many kg fruits he buy

Total fruits = Weight of Apples + Weight of Guavas + Weight of Oranges

Total fruits = $\dfrac{9}{2}+\dfrac{11}{4}+\dfrac{16}{5}$

                                                                                 

Now we have take the LCM of 2, 4 and 5

$\begin{array}{r | 1} 2 & 2,4,5 \\ \cline{2-2} 2 & 1,2,5 \\ \cline{2-2} 5 & 1,1,5 \\ \cline{2-2} & 1,1,1\end{array}$

LCM of 2, 2 and 5 = 2 × 2 × 5 = 20

                                                                           

Now we have to make denominator same and solve the problem.

$\implies\dfrac{9}{2}+\dfrac{11}{4}+\dfrac{16}{5}\\\\\\\implies\dfrac{90+55+64}{20}\\\\\\\implies\boxed{\bold{\dfrac{209}{20}kg}}$

Or 10.45 kg answer
