Answer 1

Option A -
`4(2)/(3)*11(1)/(4)=52(1)/(2)`

Explanation:

Given : Numbers
`4(2)/(3)` and
`11(1)/(4)`

To find : What's the product of number ?

Solution :

Step 1 - Write the number in product form,

`4(2)/(3)*11(1)/(4)`

Step 2 - Write the mixed fraction into simpler fraction,

`4(2)/(3)*11(1)/(4)=(14)/(3)* (45)/(4)`

Step 3 - Multiply the numerator by numerator and denominator by denominator,

`4(2)/(3)*11(1)/(4)=(630)/(12)`

Step 4 - Write in simpler form,,

`4(2)/(3)*11(1)/(4)=(105)/(2)`

Step 5 - Write in mixed fraction,

`4(2)/(3)*11(1)/(4)=52(1)/(2)`

Therefore,Option A is correct.

Answer 2

4 2/3 * 11 1 /4

change to improper fractions

4 2/3 =(3* 4+2)/3 = 14/3

11 1/4 = (4* 11+1)/ 4 =45/4

14/3 * 45/4 = 630/12

105/2

52 1/2
