Answer 2

Answer:

and we don't know the table of fractions to divide so we need to multiply

Therefore,

2 2/7×15 3/4 × 2 1/4÷4/7× 2 5/8

as we know that every mixed fractions has to be converted into improper fraction

so let's convert 2 2/7 firstly

so we will multiply 7 and 2 and after multiplying we will add 2 in it:

7×2+2

We get ,

16/7 as an imroper fraction of 2 2/7

now let's convert the second mixed fraction that is 15 3/4 into improper fraction :

4×15+3

We get,

63/4 as an imroper fraction of 15 3/4

so let's convert the third mixed fraction that is 2 1/4

4×2+1

We get ,

9/4 as an improper fraction of 2 1/4

now we will directly convert 2 5/8 because 4/7 isn't a mixed fraction

2 5/8 :

8×2+5

We get,

21/8 as an improper fraction of 2 5 /8

now we have converted every mixed fractions to improper now it's time to multiply

first 2 2/7 that is 16/7

second is 15 3/4 that is 63/4

so 16 /7 × 63/4

so multiply
