Question

27. A farmer divides his herd of cows among his

four sons so that first son gets one half of the
berd, the second son one-fourth, the third son
one fifth and the fourth son 7 cows, the total
number of cows in the herd is:
​

Answer 1

we have to find a common denominator for the fractions so

1/2 1/4 1/5

they all go into 20

so

10/20 5/20 4/20

in total that is 19/20

so the last son has 1/20 which is seven

so 20/20 is 20 times that amount which is 140

140 cows

Answer 2

we have to find a common denominator for the fractions so
1/2 1/4 1/5
they all go into 20
so
10/20 5/20 4/20
in total that is 19/20
so the last son has 1/20 which is seven
so 20/20 is 20 times that amount which is 140

140 cows
