Answer 1

${\huge{\color{pink}\star{\mathfrak{\color{pink}{\underline{\underline{Answer :}}}}}}}$

Jack's stride = 64 cm

Jill's stride = 56 cm

for getting the desired answer we have to find LCM of these numbers,

Therefore,

LCM OF 64 AND 56 :

64 = 2 x 2 x 2 x 2 x 2 x 2

56 = 2 x 2 x 2 x 7

Answer 2

Answer:

Step-by-step explanation:

Given :-

Jack's stride = 64 cm  

Jill's stride = 56 cm

To Find :-

Distance they walked

Solution :-

To find the distance walked, we need to find LCM of these two numbers,

LCM OF 64 AND 56 :-  

64 = 2 x 2 x 2 x 2 x 2 x 2

56 = 2 x 2 x 2 x 7

LCM = 2 × 2 × 2 × 2 × 2 × 2 × 7

LCM = 448 cm

Hence, they walked 448 cm.
