Question

2/5 of 5/7 divide (7/5 - 1/7) +(4/5+1/4)

Answer 1

Answer:

2/5 of 5/7 / (7/5 - 1/7) +(4/5+1/4)=281/220.

Step-by-step explanation:

2/5 of 5/7 / (7/5 - 1/7) +(4/5+1/4)

=> Follow B.O.D.M.A.S Rule

so, brackets first=

(7/5 - 1/7) Find LCM= 35

=> (49/35 - 5/35) = 44/35

now the second one

(4/5 + 1/4) LCM= 20

=> (16/20 + 5/20) = 21/20

2/5 of 5/7 / 44/35 + 21/20

then next is Of

2/5 of 5/7 = 2/5*5/7 = 10/35 reduced to 2/7

2/7 / 44/35 + 21/20

next division

=> 2/7 / 44/35 this bold underlined shall be inverses to 35/44 because the fraction to be divided by is inverses in division!!

2/7 * 35/44 = 5/22 in reduced form!!

5/22 + 21/20

then we need to just add but first we need to find LCM= 220

50/220 + 231/220= 281/220.

we finish here but you can cross check!!
