Answer:

1. C 2. D 3. A 4. B 5. B

Step-by-step explanation:

1. 5/8 divided by 1/4

first flip the second fraction so: 5/8 divided by 4/1

then instead of divide make it multiplication

5/8 x 4/1 = 20/8

multiply. since this isn't lowest term we will divide it with 4 20/8 divide by 4 = 5/2 or 2 1/2

2. 1/6 divide 2/3.

just like the other one make the second flip the second fraction and make it multiplication

1/6 x 3/2 = 3/12 divde to 3 to make it lowest term

multiply

3/12 divide 3 = 1/4

3. 2/5 divide 9/10

just like the other one make the second flip the second fraction and make it multiplication

2/5 x 10/9 = 20/45 divide to 5 to make it lowest term 20/45 divide by 5 = 4/9

4. 3/8 divide by 5/12

just like the other one make the second flip the second fraction and make it multiplication

3/8 x 12/5 = 36/40 divide by 4 = 9/10

5. 12 divide by 4/5

just like the other one make the second flip the second fraction and make it multiplication also make the 12's denominator 1

12/1 x 5/4 = 60/4 divide it by 4 = 15/1 or just 15
