Answer:

let us first start with some basic information ~
A fraction can be represented as
where ,
x is the numerator and y is the denominator !
the question asks us to do something that will help us get same denominator for both the terms !
so let's see what we should do in such a case ~

and we're done !
let's add some more info to be lil more clear ~
while converting the denominator of both the terms , we must multiply the same number ( this number refers to the one we'll have to multiply to the denominator to obtain the desired result ) with the denominator as well as with the numerator !
hope helpful :D
The correct answer is 6 × (7 + 2) - 1 = 53. This is because in the Order of Operations, multiplying comes first. So to make sure you get the right answer, you have to put the 7 + 2 in parentheses to get 6 × 9 - 1 and not 6 × 7 + 1.
