Also find the weigh they are carrying together. Pls help me...​

Answer 1

Answer:

Step-by-step explanation:

Richa' s weight =

1 1/2 kg rice + 2 1/4 kg lentils + 1 kg sugar

=> In inproper fraction => 1 1/2 = 3/2 kg  and  2 1/4 = 9/4 kg  and  1 = 1/1 kg

=> 3/2 + 9/4 + 1/1

=> 6/4 + 9/4 + 4/4             ( LCM of 2, 4 and 1 is 4)

=> 19/4 kg of weight.

Rachit's weight =

2 1/2 kg apples + 1 3/4 kg oranges + 1 kg grapes

=>  In improper fraction => 2 1/2 = 5/2 kg  and  1 3/4 = 7/4 kg  and 1 = 1/1 kg\

=> 5/2 + 7/4 + 1/1

=> 10/4 + 7/4 + 4/4            ( LCM of 2, 4 and 1 is 4 )

=> 21/4 kg of weight.

Total weight =

=> 19/4 + 21/4                    ( Richa's weight + Rachit's weight)

=> 40/4                              

=> 10/1 = 10 kg of weight.    ( Simplifing the answer)
