Respuesta :

6 2/3 - 1 1/4 

Solutions 

1) Subtract the whole numbers 
6 - 1 = 5 

2) Simplify fractions 2/3 and 1/4 
⇒ Since the denominators are different we have to make them same. To make the denominators same you have to multiply by the least common multiple 
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

List out all multiples of each denominator, and find the first common one.
3 ⇒: 3,6,9,12
4 ⇒ : 4,8,12 

The first common denominator of 3 and 4 is 12 so therefore the LCD of 2/3 and 1/4 is 12. 

Both of the denominator are gonna be 12. 

⇒ Multiply 3 and 4 until they reach 12. 

3 = 
3 x 1 = 3
3 x 2 = 6 
3 x 3 = 9 
3 x 4 = 12 

4 = 
4 x 1 = 4 
4 x 2 = 8 
4 x 3 = 12

3 x 4 = 12 
4 x 3 = 12

1)  Make the denominators the same as the LCD.
2×4          1 x 3 
______ - ________  
3×4        4 x 3 
2) Simplify. Denominators are now the same

3) Subtract the numerators 
[tex] \frac{8-3}{12} [/tex]

5) Simplify 
[tex] \frac{5}{12} [/tex] 

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

Simplify 

1) Whole number = 5 
2) Fraction = [tex] \frac{5}{12} [/tex]  

Add them together 

5 [tex] \frac{5}{12} [/tex]
