Question

What 6 7/8 decrease by 2 2/5

Answer 1

Answer

-179/40

Step by step explanation.

2 2/5 - 6 7/8

12/5 - 55/8

96/40-275/40

-179/40

Above the two numbers are in mixed fraction so we will convert that into improper fraction by 5×2+2 let the dinominator be same and that is 5 so we will get 12/5.Then we will do the same thing with 6 7/8 that is 8×6+7 is equal to 55 let the dinominator be same that is 8 so we will get 55/8.Then here the dinominators are different that is 5 & 8 so we will make them same by that we will get 96/40 & 275/40 then subtract 96-275/40 then we will get -179/40.

I hope u understood?
