Answer 2

Answer:

Required value of 1 1/15 + 3 3/10 - 2 4/5 is 43 / 6.

Step-by-step explanation:

Given term sequence is $1\dfrac{1}{15}+3\dfrac{3}{10}-2\dfrac{4}{5}$

Given terms are in mixed fractions, we have to make them in a simple fraction.

= > 1 1/15 + 3 3/10 -2 4/5

Converting mixed fractions in simpler form :

Suppose a mixed fraction $x\dfrac{a}{b}$, in simplest form it should be $\dfrac{bx+a}{b}$

= > { ( 15 x 1 ) + 1 } / 15 + { ( 10 x 3 ) + 3 } / 10 - { ( 2 x 5 ) + 4 } / 5

= > { 15 + 1 } / 15 + { 30 + 3 } / 10 + { 10 + 4 } / 5

= > 16 / 15 + 33 / 10 + 14 / 5

= > ( 16 x 10 x 5 ) / ( 15 x 10 x 5 ) + ( 33 x 15 x 5 ) / ( 10 x 15 x 5 ) + ( 14 x 15 x 10 ) / ( 5 x 15 x 10 )

= > 800 / 750 + 2475 / 750 + 2100 / 750

= > ( 800 + 2475 + 2100 ) / 750

= > 5375 / 750

= > 43 / 6

Hence the required value of 1 1/15 + 3 3/10 - 2 4/5 is 43 / 6.
