Pls help with these

Step-by-step explanation:

Question 1 : d) 6 2/6 - 3 2/8

both 6 and 8 can get multiplied by each other to get 48 as denominator to make things easier.

=> 6 2*8/6*8 - 3 2*6/8*6

=> 6 16/48 - 3 12/48

We can break the subtraction into subtraction of the whole number and subtraction of fraction

=> (6-3) (16/48-12/48)

=> 3 4/48

Question 2 : c) 10 22/40

5 6/8 + 4 4/5

First let's change these improper fractions, we get,

46/8 + 24/5

LCM = 40,

=> 46*5/8*5 + 24*8/5*8

=> 230/40 + 192/40

=> 422/40

=> 10 22/40

Question 3 : b) 4 1/8 + 4 1/3

LCM = 24

=> 4 1*3/8*3 + 4 1*8/3*8

=> 4 3/24 + 4 8/24

Like question 1, let us do it the whole number and fraction separately,

(4+4) (3/24+8/24)

8 11/24
