Question

For Numbers 14a-14d, tell which expressions require you to rename mixed numbers before you can subtract. Find each difference. Write each expression and the difference as an equation in the correct box 14a 2 1/3-1 3/4. 14b 1 3/4 -7/8. 14c 5 2/3-2 1/3. 14d 6 1/5-2 1/3

Answer 1

The answer would be 142 degrees

Answer 2

14 a, 14 c, 14 d are the Expressions which require to rename mixed numbers before we can subtract.

14 a. →

`=2 (1)/(3)-1 (3)/(4)\\\\= (7)/(3)-(7)/(4)\\\\= (28-21)/(12) \\\\= (7)/(12)`

14 b.

`1 (3)/(4) -(7)/(8)\\\\ = (7)/(4)-(7)/(8) \\\\ =(14-7)/(8) \\\\ =(7)/(8)`

14 c.

`5 (2)/(3)-2 (1)/(3)\\\\ = (17)/(3)-(7)/(3) \\\\ =(17-7)/(3)\\\\ =(10)/(3)=3 (1)/(3)`

14 d.

`6\frac {1}{5}-2 (1)/(3)\\\\ = (31)/(5)-(7)/(3) \\\\ = (93-35)/(15)=(58)/(15)=3 (13)/(15)`
