Misalkan M menyatakan harga 1 buku tulis dan N menyatakan harga 1 bolpoin. Dengan demikian, harga 3 buku tulis adalah 3m, harga 5 bolpoin 5n dan total harga adalah Rp19.000,00. Persamaan linear dua variabel dapat dituliskan sebagai berikut. 3m + 5n = 19.000 Terimakasih ⚘ tolong dijawab secepatnya ya

Before you can add or subtract fractions, they must have a common denominator.
-- Find a common denominator for [ something/3 ] and [ something/4 ].
-- When you have both of the fractions changed to a common denominator, you can just subtract the second numerator from the first one, and write that difference over the same common denominator.

The **equivalent **value of the **fraction **is A = 5/12
Given data ,
Let the **equation **be represented as A
Now , the value of A is
Let the first **fraction **be p
where the value of p = 2/3
Let the second fraction be q
where q = 1/4
Now , the **fraction **is A = p - q
On simplifying the expression , we get
So , the left hand side of the **equation **is equated to the right hand side by the value of p - q
A = 2/3 - 1/4
A = ( 8 - 3 ) / 12
On further simplification , we get
A = 5/12
Therefore , the value of A = 0.4166667
Hence , the **expression **is A = 5/12
