Question

Please help me find the same denominator

Answer 1

Explanation:

you have to multiply first fraction with '8' and second fraction with '10' :

the fractions will become 72/80 and 70/80 then you can compare it

Answer 2

`\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}`

let us first start with some basic information ~

A fraction can be represented as
`(x)/(y)\\` 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 ~

`(9)/(10) \: and \: (7)/(8) \\ \\ \\ lets \: make \: the \: denominator \: of \: both \\ the \: terms \: reach \: 80 \: , \\ \\ \bold\orange{ \implies \: (9)/(10) * (8)/(8) = }\bold\red{ (72)/(80)} \\ \\\bold\orange{ \implies \: (7)/(8) * (10)/(10) =}\bold\red{ (70)/(80)}`

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
