Answer 2

Question

sara can walk 6 3/4 km in an hour. how much distance will she cover in 3 1/2 hours

Solutions

Sara can walk in an hour = 6 3/4

the distance covered in 3 1/2 hours = X

thus ,

Let me know the distance covered in 3 1/2 h =

To find

6 3/4 = (6*4+3) 27/4

3 1/2 =. ( 3*2+1) 7/2

therefore,

27/4 × 7/2

crossing canceling

27*2 = it is not multiple of each other

4*7 = it is not multiple of each other.

so,

there will multiple dinominator with denominator

and numerators with numerators..

27/7 (*) = 189 km

4/2 (*) = 8 km

your answer is 189/8 km

189 / 8 = in fraction 23 5/8 km
