Question

plz explain how there come 3×1 6×1 4×5​

Answer 1

→ 3-6-20 is ans is near to 45.8

5

Answer 2

Step-by-step explanation:

via taking LCM

we multiple with a no. with both numerator & denominator

as lcm of 8,4,6 is 24

then in 1/8 for making the denominator(8 here) 24 we should multiply it with 3 (8 *×3) as 24/8 =3.

we have to multiply 3 with the numerator also (1 × 3 here)

so it will give 3/24

again, in 1/4

by doing the same we will multiply (24/4)= 6 to both numerator &denominator

here it will give 6/24

again, in 5/6

we will multiply (24/6) = 4 to both numerator & denominator

and here it will give 20/24

so itt will be 3/24 - 6/ 24 +20/24

now all have the same value of denominator and we can simply operate them.

== 17/24.
