Please help me to solve this out​

Answer 1

Answer:

a)146/15 b)67/20

Step-by-step explanation:

a) 4 1/3 +5 2/5

= 13/3+27/5

=65+81/15

=146/15

b) 3 3/4-2/5

=15/4-2/5

=75-8/20

=67/20

Answer 2

Hey there!

First by resolving the mixed fraction into improper fraction we get :

a) 13/3 + 27/5

• Now take LCM

• LCM of 3 and 5 is 15

• Now let's make the denominators equal :

13*5 / 3*5 = 65/15 -----(1)

And

27*3/ 5*3 = 81 /15 ------(2)

Now add (1) and (2) :

65 + 81/15

= 146/15



Hence, answer for a) is 146 /5

Similarly, in b) First by resolving the mixed fraction into improper fraction we get :

b.) 15/4 - 2/5

• Now take LCM

• LCM of 4 and 5 is 20

• Now let's make the denominators equal :

15 *5 / 4*5 = 75/20 -----(1)

2*4/5*4 = 8/20 ----(2)

Now subtract (2) from (1) :

75 - 8/ 20 = 67/20

Hence, the answer for b) 67/20
