Estimate the answer by rounding each fraction to the nearest whole number and then subtracting.
A. 5
B. 3
C. 3 1/2
D. 3 1/12

Answer 1

D. 3 1/12

Step-by-step explanation:

`\rightarrow \sf 4(1)/(3) -1(1)/(4)`

convert into improper fraction

`\rightarrow \sf (13)/(3) -(5)/(4)`

make the denominators same. 12 is the common factor of both 3 and 4

`\rightarrow \sf (13(4))/(12) -(5(3))/(12)`

simplify

`\rightarrow \sf (52)/(12) -(15)/(12)`

join both fraction

`\rightarrow \sf (52-15)/(12)`

simplify

`\rightarrow \sf (37)/(12)`

convert into mixed fraction

`\rightarrow \sf 3(1)/(12)`
