Answer:

10/16 is not equivalent to ⅔.

⅛+¾=⅞

Explanation:

To simplify to simplest form find the GCF for both and divide on each side.


(10)/(15) = (2)/(3)

the GCF is 5, so you divide the numerator and denominator by 5 to get 2/3.


(4)/(6) = (2)/(3)

When you divide the numerator and denominator by 2 (GCF) it would be ⅔.


(12)/(18) = (2)/(3)

when you divide both the numerator and denominator by 6 (GCF) you get ⅔.


(10)/(16) = (5)/(8)

when you divide the numerator and denominator by 2 (gcf) you get ⅝.

therefore, 10/16 is not equivalent.


(1)/(8) + (3)/(4) =

Find the LCM

Least Common Multiple is 16.

8: 8, 16

4: 4, 8, 12, 16


(2)/(16) + (12)/(16)

for ⅛ you multiply the numerator and denominator by 2 to get 2/16. do the same with 3/4 but with 4 to get 12/16


(2)/(16) + (12)/(16) = (14)/(16)

you can simplify by dividinv both sides by 2 to get 7/8.
