Answer:

1. 115

2. 2 3/4

3. 48

4. 1/4

5. 15 4/35

Step-by-step explanation:

1. 5 3/4 x 20

Solution:

Step 1:

Make the Mixed Number into Improper Fraction

5 x 4 + 3= 23 so 23 is your numerator and copy the denominator so it would be 23/4 then add an imaginary 1 in 20

Step 2:

How to multiply fractions:

In traditional method, multiply 23 and 20 = 460 that would be your numerator and 4 x 1 is 4, that would be your denominator

23    x    20   =   460

4              1    = 4  

then divide 460 divided by 4 is 115

2. 11/15 x 3 3/4

 11  x   15  = 165  

 15     4    = 60

165/60 to mixed fraction is 2 45/60

2 45/60 llowest term is 2 3/4 so final answer is 2 3/4

3. 14 x 3 3/7

 14   x  24 = 336

  1         7   =7

336/7 becomes mixed fraction = 48

4. 1/2 x 2/3 x 3/4

  1 x 2 x 3= 6

  2  3    4= 24

6/24 lowest term is 1/4

5. 4 3/5 x 3 2/7

  23 x 23= 529

  5     7 = 35

529/35

15 4/35
