Work out the following, giving your answer in the simplest form <br> A) 4/7 divided by 1 3/4
spayn [35]

Answer:

The answer to your question is 16/49

Step-by-step explanation:

Data

4/7 ÷ 1 3/4

Process

1.- Convert the mixed fractions into improper fractions

1 3/4 = (4 + 3) / 4 = 7/4

2.- Divide

       4/7 ÷ 7/4 = 16/49

3.- Simplify

I think it is not possible to simplify.

4.- Also we can solve this problem by converting the division into a multiplication, just invert the second fraction.

      4/7 x 4/7 = 16/49

The result is the same.
