Question

There is 7/8 kg of salt in the kitchen. Mrs.Gupta used 2/15 of the salt when she is preparing dinner. How much salt did she use?

Answer 1

Answer:

Find the least common denominator or LCM of the two denominators:

LCM of 15 and 8 is 120

For the 1st fraction, since 15 × 8 = 120,

2 /15 =  

2 × 8 /15 × 8

=  16 /20

Likewise, for the 2nd fraction, since 8 × 15 = 120,

7 /8=

7 × 15 /8 × 15

=  105 /120

Subtract the two fractions:

16 /120  -  105 /120

=  16 - 105 /120

=  -89 /120
