Verified answer

Option (a)

Step-by-step explanation:

Given :-

| (1/5)- (2/7) |

To find :-

Find the value of | (1/5)- (2/7) | ?

Solution :-

Given that : | (1/5)- (2/7) |

The denominators are 5 and 7

LCM of 5 and 7 = 35

=> | [(1×7)-(2×5)]/35 |

=> | (7-10)/35 |

=> | (-3/35) |

=> 3/35

Answer:-

The value of | (1/5)- (2/7) | is 3/35

Used formulae :-

• The absolute value or modulus of a real number x is denoted by |x|.
• x is the non-negative value of x without regard to its sign.
• |x| = x if x is positive.
• |x| = −x if x is negative (in which case −x is positive).
• |0| = 0.

Step-by-step explanation:

LCM of 5 and 7= 35

1/5 × 7/7= 7/35

-2/7 × 5/5= -(10/35)

=> (7-10)/35

=> -(3/35)

=> (-3)/(-35)

=> 3/35

Therefore, The required solution is 3/35.
